Given numbers are 620, 664, 761, 634

The list of prime factors of all numbers are

Prime factors of 620 are 2 x 2 x 5 x 31

Prime factors of 664 are 2 x 2 x 2 x 83

Prime factors of 761 are 761

Prime factors of 634 are 2 x 317

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

Given numbers are 620, 664, 761, 634

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

Apply this formula for all numbers.

Step1:

LCM(620, 664) = 102920

GCD(620, 664) = ( 620 x 664 ) / 102920

= 620 / 664

= 620

Step2:

LCM(4, 761) = 3044

GCD(4, 761) = ( 4 x 761 ) / 3044

= 4 / 761

= 4

Step3:

LCM(1, 634) = 634

GCD(1, 634) = ( 1 x 634 ) / 634

= 1 / 634

= 1

So, Greatest Common Divisor of 620, 664, 761, 634 is 1
