Given numbers are 661, 715, 407, 250

The list of prime factors of all numbers are

Prime factors of 661 are 661

Prime factors of 715 are 5 x 11 x 13

Prime factors of 407 are 11 x 37

Prime factors of 250 are 2 x 5 x 5 x 5

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

Given numbers are 661, 715, 407, 250

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

Apply this formula for all numbers.

Step1:

LCM(661, 715) = 472615

GCD(661, 715) = ( 661 x 715 ) / 472615

= 661 / 715

= 661

Step2:

LCM(1, 407) = 407

GCD(1, 407) = ( 1 x 407 ) / 407

= 1 / 407

= 1

Step3:

LCM(1, 250) = 250

GCD(1, 250) = ( 1 x 250 ) / 250

= 1 / 250

= 1

So, Greatest Common Divisor of 661, 715, 407, 250 is 1
