GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(228, 646) = 3876
GCD(228, 646) = ( 228 x 646 ) / 3876
= 228 / 646
= 228
Step2:
LCM(38, 221) = 8398
GCD(38, 221) = ( 38 x 221 ) / 8398
= 38 / 221
= 38
Step3:
LCM(1, 849) = 849
GCD(1, 849) = ( 1 x 849 ) / 849
= 1 / 849
= 1
So, Greatest Common Divisor of 228, 646, 221, 849 is 1
