Given numbers are 987, 120, 325, 779
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(987, 120) = 39480
GCD(987, 120) = ( 987 x 120 ) / 39480
= 987 / 120
= 987
Step2:
LCM(3, 325) = 975
GCD(3, 325) = ( 3 x 325 ) / 975
= 3 / 325
= 3
Step3:
LCM(1, 779) = 779
GCD(1, 779) = ( 1 x 779 ) / 779
= 1 / 779
= 1
So, Greatest Common Divisor of 987, 120, 325, 779 is 1
