Given numbers are 677, 128, 610, 878
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(677, 128) = 86656
GCD(677, 128) = ( 677 x 128 ) / 86656
= 677 / 128
= 677
Step2:
LCM(1, 610) = 610
GCD(1, 610) = ( 1 x 610 ) / 610
= 1 / 610
= 1
Step3:
LCM(1, 878) = 878
GCD(1, 878) = ( 1 x 878 ) / 878
= 1 / 878
= 1
So, Greatest Common Divisor of 677, 128, 610, 878 is 1
