Given numbers are 984, 330, 661, 687
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(984, 330) = 54120
GCD(984, 330) = ( 984 x 330 ) / 54120
= 984 / 330
= 984
Step2:
LCM(6, 661) = 3966
GCD(6, 661) = ( 6 x 661 ) / 3966
= 6 / 661
= 6
Step3:
LCM(1, 687) = 687
GCD(1, 687) = ( 1 x 687 ) / 687
= 1 / 687
= 1
So, Greatest Common Divisor of 984, 330, 661, 687 is 1
