Given numbers are 634, 693, 661, 440

The list of prime factors of all numbers are

Prime factors of 634 are 2 x 317

Prime factors of 693 are 3 x 3 x 7 x 11

Prime factors of 661 are 661

Prime factors of 440 are 2 x 2 x 2 x 5 x 11

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

Given numbers are 634, 693, 661, 440

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

Apply this formula for all numbers.

Step1:

LCM(634, 693) = 439362

GCD(634, 693) = ( 634 x 693 ) / 439362

= 634 / 693

= 634

Step2:

LCM(1, 661) = 661

GCD(1, 661) = ( 1 x 661 ) / 661

= 1 / 661

= 1

Step3:

LCM(1, 440) = 440

GCD(1, 440) = ( 1 x 440 ) / 440

= 1 / 440

= 1

So, Greatest Common Divisor of 634, 693, 661, 440 is 1
