Given numbers are 422, 280, 705

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

Apply this formula for all numbers.

Step1:

LCM(422, 280) = 59080

GCD(422, 280) = ( 422 x 280 ) / 59080

= 422 / 280

= 422

Step2:

LCM(2, 705) = 1410

GCD(2, 705) = ( 2 x 705 ) / 1410

= 2 / 705

= 2

So, Greatest Common Divisor of 422, 280, 705 is 1
