Given numbers are 386, 709, 280

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

Apply this formula for all numbers.

Step1:

LCM(386, 709) = 273674

GCD(386, 709) = ( 386 x 709 ) / 273674

= 386 / 709

= 386

Step2:

LCM(1, 280) = 280

GCD(1, 280) = ( 1 x 280 ) / 280

= 1 / 280

= 1

So, Greatest Common Divisor of 386, 709, 280 is 1
