Given numbers are 577, 858, 416, 644

The list of prime factors of all numbers are

Prime factors of 577 are 577

Prime factors of 858 are 2 x 3 x 11 x 13

Prime factors of 416 are 2 x 2 x 2 x 2 x 2 x 13

Prime factors of 644 are 2 x 2 x 7 x 23

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

Given numbers are 577, 858, 416, 644

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

Apply this formula for all numbers.

Step1:

LCM(577, 858) = 495066

GCD(577, 858) = ( 577 x 858 ) / 495066

= 577 / 858

= 577

Step2:

LCM(1, 416) = 416

GCD(1, 416) = ( 1 x 416 ) / 416

= 1 / 416

= 1

Step3:

LCM(1, 644) = 644

GCD(1, 644) = ( 1 x 644 ) / 644

= 1 / 644

= 1

So, Greatest Common Divisor of 577, 858, 416, 644 is 1
