Given numbers are 644, 928, 961, 756

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

Apply this formula for all numbers.

Step1:

LCM(644, 928) = 149408

GCD(644, 928) = ( 644 x 928 ) / 149408

= 644 / 928

= 644

Step2:

LCM(4, 961) = 3844

GCD(4, 961) = ( 4 x 961 ) / 3844

= 4 / 961

= 4

Step3:

LCM(1, 756) = 756

GCD(1, 756) = ( 1 x 756 ) / 756

= 1 / 756

= 1

So, Greatest Common Divisor of 644, 928, 961, 756 is 1
