Given numbers are 987, 858, 399, 353

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

Apply this formula for all numbers.

Step1:

LCM(987, 858) = 282282

GCD(987, 858) = ( 987 x 858 ) / 282282

= 987 / 858

= 987

Step2:

LCM(3, 399) = 399

GCD(3, 399) = ( 3 x 399 ) / 399

= 3 / 399

= 3

Step3:

LCM(3, 353) = 1059

GCD(3, 353) = ( 3 x 353 ) / 1059

= 3 / 353

= 3

So, Greatest Common Divisor of 987, 858, 399, 353 is 1
