GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(399, 891) = 118503
GCD(399, 891) = ( 399 x 891 ) / 118503
= 399 / 891
= 399
Step2:
LCM(3, 812) = 2436
GCD(3, 812) = ( 3 x 812 ) / 2436
= 3 / 812
= 3
Step3:
LCM(1, 976) = 976
GCD(1, 976) = ( 1 x 976 ) / 976
= 1 / 976
= 1
So, Greatest Common Divisor of 399, 891, 812, 976 is 1
