Given numbers are 662, 845, 438

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

Apply this formula for all numbers.

Step1:

LCM(662, 845) = 559390

GCD(662, 845) = ( 662 x 845 ) / 559390

= 662 / 845

= 662

Step2:

LCM(1, 438) = 438

GCD(1, 438) = ( 1 x 438 ) / 438

= 1 / 438

= 1

So, Greatest Common Divisor of 662, 845, 438 is 1
