Given numbers are 987, 237, 415, 385
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(987, 237) = 77973
GCD(987, 237) = ( 987 x 237 ) / 77973
= 987 / 237
= 987
Step2:
LCM(3, 415) = 1245
GCD(3, 415) = ( 3 x 415 ) / 1245
= 3 / 415
= 3
Step3:
LCM(1, 385) = 385
GCD(1, 385) = ( 1 x 385 ) / 385
= 1 / 385
= 1
So, Greatest Common Divisor of 987, 237, 415, 385 is 1
