Given numbers are 643, 852, 831

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

Apply this formula for all numbers.

Step1:

LCM(643, 852) = 547836

GCD(643, 852) = ( 643 x 852 ) / 547836

= 643 / 852

= 643

Step2:

LCM(1, 831) = 831

GCD(1, 831) = ( 1 x 831 ) / 831

= 1 / 831

= 1

So, Greatest Common Divisor of 643, 852, 831 is 1
