Given numbers are 649, 629, 920, 108

The list of prime factors of all numbers are

Prime factors of 649 are 11 x 59

Prime factors of 629 are 17 x 37

Prime factors of 920 are 2 x 2 x 2 x 5 x 23

Prime factors of 108 are 2 x 2 x 3 x 3 x 3

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

Given numbers are 649, 629, 920, 108

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

Apply this formula for all numbers.

Step1:

LCM(649, 629) = 408221

GCD(649, 629) = ( 649 x 629 ) / 408221

= 649 / 629

= 649

Step2:

LCM(1, 920) = 920

GCD(1, 920) = ( 1 x 920 ) / 920

= 1 / 920

= 1

Step3:

LCM(1, 108) = 108

GCD(1, 108) = ( 1 x 108 ) / 108

= 1 / 108

= 1

So, Greatest Common Divisor of 649, 629, 920, 108 is 1
