Given numbers are 381, 781, 670

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

Apply this formula for all numbers.

Step1:

LCM(381, 781) = 297561

GCD(381, 781) = ( 381 x 781 ) / 297561

= 381 / 781

= 381

Step2:

LCM(1, 670) = 670

GCD(1, 670) = ( 1 x 670 ) / 670

= 1 / 670

= 1

So, Greatest Common Divisor of 381, 781, 670 is 1
