Given numbers are 987, 561, 374, 483
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(987, 561) = 184569
GCD(987, 561) = ( 987 x 561 ) / 184569
= 987 / 561
= 987
Step2:
LCM(3, 374) = 1122
GCD(3, 374) = ( 3 x 374 ) / 1122
= 3 / 374
= 3
Step3:
LCM(1, 483) = 483
GCD(1, 483) = ( 1 x 483 ) / 483
= 1 / 483
= 1
So, Greatest Common Divisor of 987, 561, 374, 483 is 1
