Given numbers are 715, 742, 861, 258

The list of prime factors of all numbers are

Prime factors of 715 are 5 x 11 x 13

Prime factors of 742 are 2 x 7 x 53

Prime factors of 861 are 3 x 7 x 41

Prime factors of 258 are 2 x 3 x 43

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

Given numbers are 715, 742, 861, 258

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

Apply this formula for all numbers.

Step1:

LCM(715, 742) = 530530

GCD(715, 742) = ( 715 x 742 ) / 530530

= 715 / 742

= 715

Step2:

LCM(1, 861) = 861

GCD(1, 861) = ( 1 x 861 ) / 861

= 1 / 861

= 1

Step3:

LCM(1, 258) = 258

GCD(1, 258) = ( 1 x 258 ) / 258

= 1 / 258

= 1

So, Greatest Common Divisor of 715, 742, 861, 258 is 1
