GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(458, 920) = 210680
GCD(458, 920) = ( 458 x 920 ) / 210680
= 458 / 920
= 458
Step2:
LCM(2, 638) = 638
GCD(2, 638) = ( 2 x 638 ) / 638
= 2 / 638
= 2
Step3:
LCM(2, 274) = 274
GCD(2, 274) = ( 2 x 274 ) / 274
= 2 / 274
= 2
So, Greatest Common Divisor of 458, 920, 638, 274 is 2
