Given numbers are 625, 408, 822, 664

The list of prime factors of all numbers are

Prime factors of 625 are 5 x 5 x 5 x 5

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

Prime factors of 822 are 2 x 3 x 137

Prime factors of 664 are 2 x 2 x 2 x 83

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

Given numbers are 625, 408, 822, 664

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

Apply this formula for all numbers.

Step1:

LCM(625, 408) = 255000

GCD(625, 408) = ( 625 x 408 ) / 255000

= 625 / 408

= 625

Step2:

LCM(1, 822) = 822

GCD(1, 822) = ( 1 x 822 ) / 822

= 1 / 822

= 1

Step3:

LCM(1, 664) = 664

GCD(1, 664) = ( 1 x 664 ) / 664

= 1 / 664

= 1

So, Greatest Common Divisor of 625, 408, 822, 664 is 1
