Given numbers are 987, 345, 472, 389
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(987, 345) = 113505
GCD(987, 345) = ( 987 x 345 ) / 113505
= 987 / 345
= 987
Step2:
LCM(3, 472) = 1416
GCD(3, 472) = ( 3 x 472 ) / 1416
= 3 / 472
= 3
Step3:
LCM(1, 389) = 389
GCD(1, 389) = ( 1 x 389 ) / 389
= 1 / 389
= 1
So, Greatest Common Divisor of 987, 345, 472, 389 is 1
