GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(742, 224) = 11872
GCD(742, 224) = ( 742 x 224 ) / 11872
= 742 / 224
= 742
Step2:
LCM(14, 221) = 3094
GCD(14, 221) = ( 14 x 221 ) / 3094
= 14 / 221
= 14
So, Greatest Common Divisor of 742, 224, 221 is 1
