Given numbers are 659, 840, 591, 987

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
