Given numbers are 622, 711, 645

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

Apply this formula for all numbers.

Step1:

LCM(622, 711) = 442242

GCD(622, 711) = ( 622 x 711 ) / 442242

= 622 / 711

= 622

Step2:

LCM(1, 645) = 645

GCD(1, 645) = ( 1 x 645 ) / 645

= 1 / 645

= 1

So, Greatest Common Divisor of 622, 711, 645 is 1
