Given numbers are 643, 896, 12

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

Apply this formula for all numbers.

Step1:

LCM(643, 896) = 576128

GCD(643, 896) = ( 643 x 896 ) / 576128

= 643 / 896

= 643

Step2:

LCM(1, 12) = 12

GCD(1, 12) = ( 1 x 12 ) / 12

= 1 / 12

= 1

So, Greatest Common Divisor of 643, 896, 12 is 1
