Given numbers are 290, 637, 687

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

Apply this formula for all numbers.

Step1:

LCM(290, 637) = 184730

GCD(290, 637) = ( 290 x 637 ) / 184730

= 290 / 637

= 290

Step2:

LCM(1, 687) = 687

GCD(1, 687) = ( 1 x 687 ) / 687

= 1 / 687

= 1

So, Greatest Common Divisor of 290, 637, 687 is 1
