Given numbers are 891, 557, 815, 422
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(891, 557) = 496287
GCD(891, 557) = ( 891 x 557 ) / 496287
= 891 / 557
= 891
Step2:
LCM(1, 815) = 815
GCD(1, 815) = ( 1 x 815 ) / 815
= 1 / 815
= 1
Step3:
LCM(1, 422) = 422
GCD(1, 422) = ( 1 x 422 ) / 422
= 1 / 422
= 1
So, Greatest Common Divisor of 891, 557, 815, 422 is 1
