Given numbers are 891, 792, 868, 423
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(891, 792) = 7128
GCD(891, 792) = ( 891 x 792 ) / 7128
= 891 / 792
= 891
Step2:
LCM(99, 868) = 85932
GCD(99, 868) = ( 99 x 868 ) / 85932
= 99 / 868
= 99
Step3:
LCM(1, 423) = 423
GCD(1, 423) = ( 1 x 423 ) / 423
= 1 / 423
= 1
So, Greatest Common Divisor of 891, 792, 868, 423 is 1
