Given numbers are 661, 763, 640, 264

The list of prime factors of all numbers are

Prime factors of 661 are 661

Prime factors of 763 are 7 x 109

Prime factors of 640 are 2 x 2 x 2 x 2 x 2 x 2 x 2 x 5

Prime factors of 264 are 2 x 2 x 2 x 3 x 11

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

Given numbers are 661, 763, 640, 264

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

Apply this formula for all numbers.

Step1:

LCM(661, 763) = 504343

GCD(661, 763) = ( 661 x 763 ) / 504343

= 661 / 763

= 661

Step2:

LCM(1, 640) = 640

GCD(1, 640) = ( 1 x 640 ) / 640

= 1 / 640

= 1

Step3:

LCM(1, 264) = 264

GCD(1, 264) = ( 1 x 264 ) / 264

= 1 / 264

= 1

So, Greatest Common Divisor of 661, 763, 640, 264 is 1
