Given numbers are 649, 600, 172, 621

The list of prime factors of all numbers are

Prime factors of 649 are 11 x 59

Prime factors of 600 are 2 x 2 x 2 x 3 x 5 x 5

Prime factors of 172 are 2 x 2 x 43

Prime factors of 621 are 3 x 3 x 3 x 23

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

Given numbers are 649, 600, 172, 621

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

Apply this formula for all numbers.

Step1:

LCM(649, 600) = 389400

GCD(649, 600) = ( 649 x 600 ) / 389400

= 649 / 600

= 649

Step2:

LCM(1, 172) = 172

GCD(1, 172) = ( 1 x 172 ) / 172

= 1 / 172

= 1

Step3:

LCM(1, 621) = 621

GCD(1, 621) = ( 1 x 621 ) / 621

= 1 / 621

= 1

So, Greatest Common Divisor of 649, 600, 172, 621 is 1
