Given numbers are 646, 136, 640, 837

The list of prime factors of all numbers are

Prime factors of 646 are 2 x 17 x 19

Prime factors of 136 are 2 x 2 x 2 x 17

Prime factors of 640 are 2 x 2 x 2 x 2 x 2 x 2 x 2 x 5

Prime factors of 837 are 3 x 3 x 3 x 31

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

Given numbers are 646, 136, 640, 837

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

Apply this formula for all numbers.

Step1:

LCM(646, 136) = 2584

GCD(646, 136) = ( 646 x 136 ) / 2584

= 646 / 136

= 646

Step2:

LCM(34, 640) = 10880

GCD(34, 640) = ( 34 x 640 ) / 10880

= 34 / 640

= 34

Step3:

LCM(2, 837) = 1674

GCD(2, 837) = ( 2 x 837 ) / 1674

= 2 / 837

= 2

So, Greatest Common Divisor of 646, 136, 640, 837 is 1
