GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(557, 385) = 214445
GCD(557, 385) = ( 557 x 385 ) / 214445
= 557 / 385
= 557
Step2:
LCM(1, 987) = 987
GCD(1, 987) = ( 1 x 987 ) / 987
= 1 / 987
= 1
Step3:
LCM(1, 658) = 658
GCD(1, 658) = ( 1 x 658 ) / 658
= 1 / 658
= 1
So, Greatest Common Divisor of 557, 385, 987, 658 is 1
