Given numbers are 154, 649, 251, 891
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(154, 649) = 9086
GCD(154, 649) = ( 154 x 649 ) / 9086
= 154 / 649
= 154
Step2:
LCM(11, 251) = 2761
GCD(11, 251) = ( 11 x 251 ) / 2761
= 11 / 251
= 11
Step3:
LCM(1, 891) = 891
GCD(1, 891) = ( 1 x 891 ) / 891
= 1 / 891
= 1
So, Greatest Common Divisor of 154, 649, 251, 891 is 1
