Given numbers are 646, 524, 550, 137

The list of prime factors of all numbers are

Prime factors of 646 are 2 x 17 x 19

Prime factors of 524 are 2 x 2 x 131

Prime factors of 550 are 2 x 5 x 5 x 11

Prime factors of 137 are 137

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

Given numbers are 646, 524, 550, 137

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

Apply this formula for all numbers.

Step1:

LCM(646, 524) = 169252

GCD(646, 524) = ( 646 x 524 ) / 169252

= 646 / 524

= 646

Step2:

LCM(2, 550) = 550

GCD(2, 550) = ( 2 x 550 ) / 550

= 2 / 550

= 2

Step3:

LCM(2, 137) = 274

GCD(2, 137) = ( 2 x 137 ) / 274

= 2 / 137

= 2

So, Greatest Common Divisor of 646, 524, 550, 137 is 1
