Given numbers are 643, 380, 951

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

Apply this formula for all numbers.

Step1:

LCM(643, 380) = 244340

GCD(643, 380) = ( 643 x 380 ) / 244340

= 643 / 380

= 643

Step2:

LCM(1, 951) = 951

GCD(1, 951) = ( 1 x 951 ) / 951

= 1 / 951

= 1

So, Greatest Common Divisor of 643, 380, 951 is 1
