Given numbers are 651, 408, 284, 620

The list of prime factors of all numbers are

Prime factors of 651 are 3 x 7 x 31

Prime factors of 408 are 2 x 2 x 2 x 3 x 17

Prime factors of 284 are 2 x 2 x 71

Prime factors of 620 are 2 x 2 x 5 x 31

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

Given numbers are 651, 408, 284, 620

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

Apply this formula for all numbers.

Step1:

LCM(651, 408) = 88536

GCD(651, 408) = ( 651 x 408 ) / 88536

= 651 / 408

= 651

Step2:

LCM(3, 284) = 852

GCD(3, 284) = ( 3 x 284 ) / 852

= 3 / 284

= 3

Step3:

LCM(1, 620) = 620

GCD(1, 620) = ( 1 x 620 ) / 620

= 1 / 620

= 1

So, Greatest Common Divisor of 651, 408, 284, 620 is 1
