Given numbers are 658, 715, 261, 717

The list of prime factors of all numbers are

Prime factors of 658 are 2 x 7 x 47

Prime factors of 715 are 5 x 11 x 13

Prime factors of 261 are 3 x 3 x 29

Prime factors of 717 are 3 x 239

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

Given numbers are 658, 715, 261, 717

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

Apply this formula for all numbers.

Step1:

LCM(658, 715) = 470470

GCD(658, 715) = ( 658 x 715 ) / 470470

= 658 / 715

= 658

Step2:

LCM(1, 261) = 261

GCD(1, 261) = ( 1 x 261 ) / 261

= 1 / 261

= 1

Step3:

LCM(1, 717) = 717

GCD(1, 717) = ( 1 x 717 ) / 717

= 1 / 717

= 1

So, Greatest Common Divisor of 658, 715, 261, 717 is 1
