Given numbers are 550, 125, 756, 644

The list of prime factors of all numbers are

Prime factors of 550 are 2 x 5 x 5 x 11

Prime factors of 125 are 5 x 5 x 5

Prime factors of 756 are 2 x 2 x 3 x 3 x 3 x 7

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 550, 125, 756, 644

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

Apply this formula for all numbers.

Step1:

LCM(550, 125) = 2750

GCD(550, 125) = ( 550 x 125 ) / 2750

= 550 / 125

= 550

Step2:

LCM(25, 756) = 18900

GCD(25, 756) = ( 25 x 756 ) / 18900

= 25 / 756

= 25

Step3:

LCM(1, 644) = 644

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

= 1 / 644

= 1

So, Greatest Common Divisor of 550, 125, 756, 644 is 1
