Given numbers are 681, 128, 781

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

Apply this formula for all numbers.

Step1:

LCM(681, 128) = 87168

GCD(681, 128) = ( 681 x 128 ) / 87168

= 681 / 128

= 681

Step2:

LCM(1, 781) = 781

GCD(1, 781) = ( 1 x 781 ) / 781

= 1 / 781

= 1

So, Greatest Common Divisor of 681, 128, 781 is 1
