Given numbers are 639, 342, 113, 723
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(639, 342) = 24282
GCD(639, 342) = ( 639 x 342 ) / 24282
= 639 / 342
= 639
Step2:
LCM(9, 113) = 1017
GCD(9, 113) = ( 9 x 113 ) / 1017
= 9 / 113
= 9
Step3:
LCM(1, 723) = 723
GCD(1, 723) = ( 1 x 723 ) / 723
= 1 / 723
= 1
So, Greatest Common Divisor of 639, 342, 113, 723 is 1
