Given numbers are 643, 794, 380

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

Apply this formula for all numbers.

Step1:

LCM(643, 794) = 510542

GCD(643, 794) = ( 643 x 794 ) / 510542

= 643 / 794

= 643

Step2:

LCM(1, 380) = 380

GCD(1, 380) = ( 1 x 380 ) / 380

= 1 / 380

= 1

So, Greatest Common Divisor of 643, 794, 380 is 1
