Given numbers are 427, 609, 474, 689

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

Apply this formula for all numbers.

Step1:

LCM(427, 609) = 37149

GCD(427, 609) = ( 427 x 609 ) / 37149

= 427 / 609

= 427

Step2:

LCM(7, 474) = 3318

GCD(7, 474) = ( 7 x 474 ) / 3318

= 7 / 474

= 7

Step3:

LCM(1, 689) = 689

GCD(1, 689) = ( 1 x 689 ) / 689

= 1 / 689

= 1

So, Greatest Common Divisor of 427, 609, 474, 689 is 1
