GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(639, 272) = 173808
GCD(639, 272) = ( 639 x 272 ) / 173808
= 639 / 272
= 639
Step2:
LCM(1, 393) = 393
GCD(1, 393) = ( 1 x 393 ) / 393
= 1 / 393
= 1
Step3:
LCM(1, 843) = 843
GCD(1, 843) = ( 1 x 843 ) / 843
= 1 / 843
= 1
So, Greatest Common Divisor of 639, 272, 393, 843 is 1
