Question

Is 83 and 120 are coprime number or not?

Answer 1

Answer:

Step-by-step explanation:

Greatest (highest) common factor (divisor)

gcf, hcf, gcd (83; 120) = 1;

Coprime numbers (relatively prime).

Numbers have no common prime factors

Answer 2

$\huge\red{ANSWER:-}$

83 is a prime number, it cannot be broken down to other prime factors;

120 = 23 × 3 × 5;

120 = 23 × 3 × 5;Calculate the greatest (highest) common factor (divisor), gcf, hcf, gcd:

120 = 23 × 3 × 5;Calculate the greatest (highest) common factor (divisor), gcf, hcf, gcd:Multiply all the common prime factors

, by the lowest exponents.

120 = 23 × 3 × 5;Calculate the greatest (highest) common factor (divisor), gcf, hcf, gcd:Multiply all the common prime factors, by the lowest exponents.

But the two numbers have no common prime factors.

120 = 23 × 3 × 5;Calculate the greatest (highest) common factor (divisor), gcf, hcf, gcd:Multiply all the common prime factors, by the lowest exponents.

But the two numbers have no common prime factors.gcf, hcf, gcd (83; 120) = 1;

120 = 23 × 3 × 5;Calculate the greatest (highest) common factor (divisor), gcf, hcf, gcd:Multiply all the common prime factors,

by the lowest exponents.But the two numbers have no common prime factors.gcf, hcf, gcd (83; 120) = 1;coprime numbers (relatively prime)

Coprime numbers (relatively prime) (83; 120)? Yes.

gcf, hcf, gcd (83; 120) = 1.

TO KNOW WHAT IS CO-PRIME WHICH MAKES YOU ALL THE SUM EASY

Two numbers are said to be co-primes if they do not share any common divisor except for 1.

Example 1:

Are numbers 6 and 25 Co-primes ?

Answer - Two given numbers are 6 and 25

Factors of 6 = 1, 2, 3, 6

Factors of 25 = 1, 5, 25

On comparing the factors of numbers 6 and 25, you can see that both have only 1 as a common factor,

Hence we can say that numbers 6 and 25 are Co-primes.

Example 2:

Are numbers 12 and 21 Co-prime ?

Answer - Two given numbers are 12 and 21

Factors of 12 = 1, 2, 3, 4, 6, 12

Factors of 21 = 1, 3, 7, 21

On comparing the factors of numbers 12 and 21, you can see that both have 1 and 3 as common factors,

Hence, we can say that numbers 12 and 21 are not Co-primes.
