Given numbers are 427, 220, 120
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(427, 220) = 93940
GCD(427, 220) = ( 427 x 220 ) / 93940
= 427 / 220
= 427
Step2:
LCM(1, 120) = 120
GCD(1, 120) = ( 1 x 120 ) / 120
= 1 / 120
= 1
So, Greatest Common Divisor of 427, 220, 120 is 1
