Given numbers are 715, 406, 20

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

Apply this formula for all numbers.

Step1:

LCM(715, 406) = 290290

GCD(715, 406) = ( 715 x 406 ) / 290290

= 715 / 406

= 715

Step2:

LCM(1, 20) = 20

GCD(1, 20) = ( 1 x 20 ) / 20

= 1 / 20

= 1

So, Greatest Common Divisor of 715, 406, 20 is 1
