GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(557, 128) = 71296
GCD(557, 128) = ( 557 x 128 ) / 71296
= 557 / 128
= 557
Step2:
LCM(1, 382) = 382
GCD(1, 382) = ( 1 x 382 ) / 382
= 1 / 382
= 1
Step3:
LCM(1, 774) = 774
GCD(1, 774) = ( 1 x 774 ) / 774
= 1 / 774
= 1
So, Greatest Common Divisor of 557, 128, 382, 774 is 1
