Question

State whether 15 and 37 are co
Prime number,​

Answer 1

Answer:

yes, 15 and 37 are co-prime.

Explanation:

co-prime numbers-

• co-prime numbers- are sets of number having only 1 as their comman - factor.

prime factorised form of 15 and 37

• 15 = 1 × 3 × 5
• 37 = 1 × 37

15 and 37 have only one common factor i.e. 1. So, They are co-prime.

Answer 2

$\huge\bold{\mathtt{Question⇒}}$

State whether 15 and 37 are co-prime numbers.

$\huge\bold{\mathtt{To\:find⇒}}$

Whether the given numbers are co-primes or not.

$\huge\bold{\mathtt{Solution⇒}}$

In mathematics, two numbers are said to be co-primes numbers if they have only 1 as their highest common factor or HCF.

First, we have to find their HCF.

The factors of:

• 15 are 1, 3, 5 and 15.

• 37 are 1 and 37.

We can see that their common factor is only 1.

So, HCF = 1

Since there HCF is 1, they are co-primes.

$\huge\bold{\mathtt{Therefore⇒}}$

Yes, 15 and 37 are co-prime numbers.
