Given numbers are 393, 156, 702, 100
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(393, 156) = 20436
GCD(393, 156) = ( 393 x 156 ) / 20436
= 393 / 156
= 393
Step2:
LCM(3, 702) = 702
GCD(3, 702) = ( 3 x 702 ) / 702
= 3 / 702
= 3
Step3:
LCM(3, 100) = 300
GCD(3, 100) = ( 3 x 100 ) / 300
= 3 / 100
= 3
So, Greatest Common Divisor of 393, 156, 702, 100 is 1
