Given numbers are 855, 129, 169, 998

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

Apply this formula for all numbers.

Step1:

LCM(855, 129) = 36765

GCD(855, 129) = ( 855 x 129 ) / 36765

= 855 / 129

= 855

Step2:

LCM(3, 169) = 507

GCD(3, 169) = ( 3 x 169 ) / 507

= 3 / 169

= 3

Step3:

LCM(1, 998) = 998

GCD(1, 998) = ( 1 x 998 ) / 998

= 1 / 998

= 1

So, Greatest Common Divisor of 855, 129, 169, 998 is 1
