Given numbers are 458, 855, 171, 637

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

Apply this formula for all numbers.

Step1:

LCM(458, 855) = 391590

GCD(458, 855) = ( 458 x 855 ) / 391590

= 458 / 855

= 458

Step2:

LCM(1, 171) = 171

GCD(1, 171) = ( 1 x 171 ) / 171

= 1 / 171

= 1

Step3:

LCM(1, 637) = 637

GCD(1, 637) = ( 1 x 637 ) / 637

= 1 / 637

= 1

So, Greatest Common Divisor of 458, 855, 171, 637 is 1
