Given numbers are 644, 180, 879, 252

The list of prime factors of all numbers are

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

Prime factors of 180 are 2 x 2 x 3 x 3 x 5

Prime factors of 879 are 3 x 293

Prime factors of 252 are 2 x 2 x 3 x 3 x 7

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

Given numbers are 644, 180, 879, 252

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

Apply this formula for all numbers.

Step1:

LCM(644, 180) = 28980

GCD(644, 180) = ( 644 x 180 ) / 28980

= 644 / 180

= 644

Step2:

LCM(4, 879) = 3516

GCD(4, 879) = ( 4 x 879 ) / 3516

= 4 / 879

= 4

Step3:

LCM(1, 252) = 252

GCD(1, 252) = ( 1 x 252 ) / 252

= 1 / 252

= 1

So, Greatest Common Divisor of 644, 180, 879, 252 is 1
