GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(254, 688) = 87376
GCD(254, 688) = ( 254 x 688 ) / 87376
= 254 / 688
= 254
Step2:
LCM(2, 396) = 396
GCD(2, 396) = ( 2 x 396 ) / 396
= 2 / 396
= 2
Step3:
LCM(2, 612) = 612
GCD(2, 612) = ( 2 x 612 ) / 612
= 2 / 612
= 2
So, Greatest Common Divisor of 254, 688, 396, 612 is 2
