Given numbers are 643, 190, 261

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

Apply this formula for all numbers.

Step1:

LCM(643, 190) = 122170

GCD(643, 190) = ( 643 x 190 ) / 122170

= 643 / 190

= 643

Step2:

LCM(1, 261) = 261

GCD(1, 261) = ( 1 x 261 ) / 261

= 1 / 261

= 1

So, Greatest Common Divisor of 643, 190, 261 is 1
