Given numbers are 403, 855, 442, 325

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

Apply this formula for all numbers.

Step1:

LCM(403, 855) = 344565

GCD(403, 855) = ( 403 x 855 ) / 344565

= 403 / 855

= 403

Step2:

LCM(1, 442) = 442

GCD(1, 442) = ( 1 x 442 ) / 442

= 1 / 442

= 1

Step3:

LCM(1, 325) = 325

GCD(1, 325) = ( 1 x 325 ) / 325

= 1 / 325

= 1

So, Greatest Common Divisor of 403, 855, 442, 325 is 1
