Given numbers are 643, 105, 416

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

Apply this formula for all numbers.

Step1:

LCM(643, 105) = 67515

GCD(643, 105) = ( 643 x 105 ) / 67515

= 643 / 105

= 643

Step2:

LCM(1, 416) = 416

GCD(1, 416) = ( 1 x 416 ) / 416

= 1 / 416

= 1

So, Greatest Common Divisor of 643, 105, 416 is 1
