Given numbers are 656, 557, 390, 166
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(656, 557) = 365392
GCD(656, 557) = ( 656 x 557 ) / 365392
= 656 / 557
= 656
Step2:
LCM(1, 390) = 390
GCD(1, 390) = ( 1 x 390 ) / 390
= 1 / 390
= 1
Step3:
LCM(1, 166) = 166
GCD(1, 166) = ( 1 x 166 ) / 166
= 1 / 166
= 1
So, Greatest Common Divisor of 656, 557, 390, 166 is 1
