Given numbers are 659, 689, 664, 580

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(659, 689) = 454051

GCD(659, 689) = ( 659 x 689 ) / 454051

= 659 / 689

= 659

Step2:

LCM(1, 664) = 664

GCD(1, 664) = ( 1 x 664 ) / 664

= 1 / 664

= 1

Step3:

LCM(1, 580) = 580

GCD(1, 580) = ( 1 x 580 ) / 580

= 1 / 580

= 1

So, Greatest Common Divisor of 659, 689, 664, 580 is 1
