GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(891, 429) = 11583
GCD(891, 429) = ( 891 x 429 ) / 11583
= 891 / 429
= 891
Step2:
LCM(33, 451) = 1353
GCD(33, 451) = ( 33 x 451 ) / 1353
= 33 / 451
= 33
Step3:
LCM(11, 777) = 8547
GCD(11, 777) = ( 11 x 777 ) / 8547
= 11 / 777
= 11
So, Greatest Common Divisor of 891, 429, 451, 777 is 1
