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

Apply this formula for all numbers.

Step1:

LCM(787, 842) = 662654

GCD(787, 842) = ( 787 x 842 ) / 662654

= 787 / 842

= 787

Step2:

LCM(1, 18) = 18

GCD(1, 18) = ( 1 x 18 ) / 18

= 1 / 18

= 1

So, Greatest Common Divisor of 787, 842, 18 is 1
