GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(660, 256) = 42240
GCD(660, 256) = ( 660 x 256 ) / 42240
= 660 / 256
= 660
Step2:
LCM(4, 688) = 688
GCD(4, 688) = ( 4 x 688 ) / 688
= 4 / 688
= 4
Step3:
LCM(4, 566) = 1132
GCD(4, 566) = ( 4 x 566 ) / 1132
= 4 / 566
= 4
So, Greatest Common Divisor of 660, 256, 688, 566 is 2
