Given numbers are 658, 258, 742, 615

The list of prime factors of all numbers are

Prime factors of 658 are 2 x 7 x 47

Prime factors of 258 are 2 x 3 x 43

Prime factors of 742 are 2 x 7 x 53

Prime factors of 615 are 3 x 5 x 41

The above numbers do not have any common prime factor. So GCD is 1

Given numbers are 658, 258, 742, 615

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(658, 258) = 84882

GCD(658, 258) = ( 658 x 258 ) / 84882

= 658 / 258

= 658

Step2:

LCM(2, 742) = 742

GCD(2, 742) = ( 2 x 742 ) / 742

= 2 / 742

= 2

Step3:

LCM(2, 615) = 1230

GCD(2, 615) = ( 2 x 615 ) / 1230

= 2 / 615

= 2

So, Greatest Common Divisor of 658, 258, 742, 615 is 1
