Given numbers are 891, 855, 18, 673

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

Apply this formula for all numbers.

Step1:

LCM(891, 855) = 84645

GCD(891, 855) = ( 891 x 855 ) / 84645

= 891 / 855

= 891

Step2:

LCM(9, 18) = 18

GCD(9, 18) = ( 9 x 18 ) / 18

= 9 / 18

= 9

Step3:

LCM(9, 673) = 6057

GCD(9, 673) = ( 9 x 673 ) / 6057

= 9 / 673

= 9

So, Greatest Common Divisor of 891, 855, 18, 673 is 1
