Given numbers are 981, 660, 587, 518
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(981, 660) = 215820
GCD(981, 660) = ( 981 x 660 ) / 215820
= 981 / 660
= 981
Step2:
LCM(3, 587) = 1761
GCD(3, 587) = ( 3 x 587 ) / 1761
= 3 / 587
= 3
Step3:
LCM(1, 518) = 518
GCD(1, 518) = ( 1 x 518 ) / 518
= 1 / 518
= 1
So, Greatest Common Divisor of 981, 660, 587, 518 is 1
