Given numbers are 646, 213, 746, 508

The list of prime factors of all numbers are

Prime factors of 646 are 2 x 17 x 19

Prime factors of 213 are 3 x 71

Prime factors of 746 are 2 x 373

Prime factors of 508 are 2 x 2 x 127

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

Given numbers are 646, 213, 746, 508

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

Apply this formula for all numbers.

Step1:

LCM(646, 213) = 137598

GCD(646, 213) = ( 646 x 213 ) / 137598

= 646 / 213

= 646

Step2:

LCM(1, 746) = 746

GCD(1, 746) = ( 1 x 746 ) / 746

= 1 / 746

= 1

Step3:

LCM(1, 508) = 508

GCD(1, 508) = ( 1 x 508 ) / 508

= 1 / 508

= 1

So, Greatest Common Divisor of 646, 213, 746, 508 is 1
