Given numbers are 408, 620, 427, 764

The list of prime factors of all numbers are

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

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

Prime factors of 427 are 7 x 61

Prime factors of 764 are 2 x 2 x 191

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

Given numbers are 408, 620, 427, 764

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

Apply this formula for all numbers.

Step1:

LCM(408, 620) = 63240

GCD(408, 620) = ( 408 x 620 ) / 63240

= 408 / 620

= 408

Step2:

LCM(4, 427) = 1708

GCD(4, 427) = ( 4 x 427 ) / 1708

= 4 / 427

= 4

Step3:

LCM(1, 764) = 764

GCD(1, 764) = ( 1 x 764 ) / 764

= 1 / 764

= 1

So, Greatest Common Divisor of 408, 620, 427, 764 is 1
