Given numbers are 987, 517, 809, 478
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(987, 517) = 10857
GCD(987, 517) = ( 987 x 517 ) / 10857
= 987 / 517
= 987
Step2:
LCM(47, 809) = 38023
GCD(47, 809) = ( 47 x 809 ) / 38023
= 47 / 809
= 47
Step3:
LCM(1, 478) = 478
GCD(1, 478) = ( 1 x 478 ) / 478
= 1 / 478
= 1
So, Greatest Common Divisor of 987, 517, 809, 478 is 1
