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

Apply this formula for all numbers.

Step1:

LCM(139, 580) = 80620

GCD(139, 580) = ( 139 x 580 ) / 80620

= 139 / 580

= 139

Step2:

LCM(1, 815) = 815

GCD(1, 815) = ( 1 x 815 ) / 815

= 1 / 815

= 1

So, Greatest Common Divisor of 139, 580, 815 is 1
