Question

determine whether 210 and 55 are co prime or not

Answer 1

Answer:

Given numbers 210 and 55 are co-prime

Step-by-step explanation:

Given two numbers 210 and 55

we have to find whether these are co-prime or not.

Two integers x and y are said to be coprime (also spelled co-prime) if the only positive integer that divides both of them is 1 i.e the GCD(Greatest common divisor) is 1.

$210=2\times 2\times 3\times 17$

$55=5\times 11$

There are no common factors therefore The greatest common divisor is 1 i.e GCD(210,55)=1

Hence, given numbers 210 and 55 are co-prime
