Given numbers are 443, 855, 342

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

Apply this formula for all numbers.

Step1:

LCM(443, 855) = 378765

GCD(443, 855) = ( 443 x 855 ) / 378765

= 443 / 855

= 443

Step2:

LCM(1, 342) = 342

GCD(1, 342) = ( 1 x 342 ) / 342

= 1 / 342

= 1

So, Greatest Common Divisor of 443, 855, 342 is 1
