Given numbers are 777, 640, 764, 961
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(777, 640) = 497280
GCD(777, 640) = ( 777 x 640 ) / 497280
= 777 / 640
= 777
Step2:
LCM(1, 764) = 764
GCD(1, 764) = ( 1 x 764 ) / 764
= 1 / 764
= 1
Step3:
LCM(1, 961) = 961
GCD(1, 961) = ( 1 x 961 ) / 961
= 1 / 961
= 1
So, Greatest Common Divisor of 777, 640, 764, 961 is 1
