Given numbers are 681, 635, 15

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

Apply this formula for all numbers.

Step1:

LCM(681, 635) = 432435

GCD(681, 635) = ( 681 x 635 ) / 432435

= 681 / 635

= 681

Step2:

LCM(1, 15) = 15

GCD(1, 15) = ( 1 x 15 ) / 15

= 1 / 15

= 1

So, Greatest Common Divisor of 681, 635, 15 is 1
