Given numbers are 436, 556, 645, 377

The list of prime factors of all numbers are

Prime factors of 436 are 2 x 2 x 109

Prime factors of 556 are 2 x 2 x 139

Prime factors of 645 are 3 x 5 x 43

Prime factors of 377 are 13 x 29

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

Given numbers are 436, 556, 645, 377

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

Apply this formula for all numbers.

Step1:

LCM(436, 556) = 60604

GCD(436, 556) = ( 436 x 556 ) / 60604

= 436 / 556

= 436

Step2:

LCM(4, 645) = 2580

GCD(4, 645) = ( 4 x 645 ) / 2580

= 4 / 645

= 4

Step3:

LCM(1, 377) = 377

GCD(1, 377) = ( 1 x 377 ) / 377

= 1 / 377

= 1

So, Greatest Common Divisor of 436, 556, 645, 377 is 1
