GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(659, 840) = 553560
GCD(659, 840) = ( 659 x 840 ) / 553560
= 659 / 840
= 659
Step2:
LCM(1, 591) = 591
GCD(1, 591) = ( 1 x 591 ) / 591
= 1 / 591
= 1
Step3:
LCM(1, 987) = 987
GCD(1, 987) = ( 1 x 987 ) / 987
= 1 / 987
= 1
So, Greatest Common Divisor of 659, 840, 591, 987 is 1
