Given numbers are 644, 475, 137, 336

The list of prime factors of all numbers are

Prime factors of 644 are 2 x 2 x 7 x 23

Prime factors of 475 are 5 x 5 x 19

Prime factors of 137 are 137

Prime factors of 336 are 2 x 2 x 2 x 2 x 3 x 7

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

Given numbers are 644, 475, 137, 336

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

Apply this formula for all numbers.

Step1:

LCM(644, 475) = 305900

GCD(644, 475) = ( 644 x 475 ) / 305900

= 644 / 475

= 644

Step2:

LCM(1, 137) = 137

GCD(1, 137) = ( 1 x 137 ) / 137

= 1 / 137

= 1

Step3:

LCM(1, 336) = 336

GCD(1, 336) = ( 1 x 336 ) / 336

= 1 / 336

= 1

So, Greatest Common Divisor of 644, 475, 137, 336 is 1
