GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(228, 143) = 32604
GCD(228, 143) = ( 228 x 143 ) / 32604
= 228 / 143
= 228
Step2:
LCM(1, 385) = 385
GCD(1, 385) = ( 1 x 385 ) / 385
= 1 / 385
= 1
Step3:
LCM(1, 721) = 721
GCD(1, 721) = ( 1 x 721 ) / 721
= 1 / 721
= 1
So, Greatest Common Divisor of 228, 143, 385, 721 is 1
