GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(129, 882) = 37926
GCD(129, 882) = ( 129 x 882 ) / 37926
= 129 / 882
= 129
Step2:
LCM(3, 812) = 2436
GCD(3, 812) = ( 3 x 812 ) / 2436
= 3 / 812
= 3
Step3:
LCM(1, 768) = 768
GCD(1, 768) = ( 1 x 768 ) / 768
= 1 / 768
= 1
So, Greatest Common Divisor of 129, 882, 812, 768 is 1
