GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(228, 144) = 2736
GCD(228, 144) = ( 228 x 144 ) / 2736
= 228 / 144
= 228
Step2:
LCM(12, 665) = 7980
GCD(12, 665) = ( 12 x 665 ) / 7980
= 12 / 665
= 12
Step3:
LCM(1, 819) = 819
GCD(1, 819) = ( 1 x 819 ) / 819
= 1 / 819
= 1
So, Greatest Common Divisor of 228, 144, 665, 819 is 1
