Given numbers are 161, 676, 649, 878
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(161, 676) = 108836
GCD(161, 676) = ( 161 x 676 ) / 108836
= 161 / 676
= 161
Step2:
LCM(1, 649) = 649
GCD(1, 649) = ( 1 x 649 ) / 649
= 1 / 649
= 1
Step3:
LCM(1, 878) = 878
GCD(1, 878) = ( 1 x 878 ) / 878
= 1 / 878
= 1
So, Greatest Common Divisor of 161, 676, 649, 878 is 1
