Given numbers are 987, 387, 126, 829
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(987, 387) = 127323
GCD(987, 387) = ( 987 x 387 ) / 127323
= 987 / 387
= 987
Step2:
LCM(3, 126) = 126
GCD(3, 126) = ( 3 x 126 ) / 126
= 3 / 126
= 3
Step3:
LCM(3, 829) = 2487
GCD(3, 829) = ( 3 x 829 ) / 2487
= 3 / 829
= 3
So, Greatest Common Divisor of 987, 387, 126, 829 is 1
