Given numbers are 126, 100, 812, 991
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(126, 100) = 6300
GCD(126, 100) = ( 126 x 100 ) / 6300
= 126 / 100
= 126
Step2:
LCM(2, 812) = 812
GCD(2, 812) = ( 2 x 812 ) / 812
= 2 / 812
= 2
Step3:
LCM(2, 991) = 1982
GCD(2, 991) = ( 2 x 991 ) / 1982
= 2 / 991
= 2
So, Greatest Common Divisor of 126, 100, 812, 991 is 1
