Given numbers are 220, 420, 228
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(220, 420) = 4620
GCD(220, 420) = ( 220 x 420 ) / 4620
= 220 / 420
= 220
Step2:
LCM(20, 228) = 1140
GCD(20, 228) = ( 20 x 228 ) / 1140
= 20 / 228
= 20
So, Greatest Common Divisor of 220, 420, 228 is 4
