GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(178, 626) = 55714
GCD(178, 626) = ( 178 x 626 ) / 55714
= 178 / 626
= 178
Step2:
LCM(2, 218) = 218
GCD(2, 218) = ( 2 x 218 ) / 218
= 2 / 218
= 2
Step3:
LCM(2, 140) = 140
GCD(2, 140) = ( 2 x 140 ) / 140
= 2 / 140
= 2
So, Greatest Common Divisor of 178, 626, 218, 140 is 2
