Given numbers are 420, 938, 502, 161
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(420, 938) = 28140
GCD(420, 938) = ( 420 x 938 ) / 28140
= 420 / 938
= 420
Step2:
LCM(14, 502) = 3514
GCD(14, 502) = ( 14 x 502 ) / 3514
= 14 / 502
= 14
Step3:
LCM(2, 161) = 322
GCD(2, 161) = ( 2 x 161 ) / 322
= 2 / 161
= 2
So, Greatest Common Divisor of 420, 938, 502, 161 is 1
