Given numbers are 191, 402, 646

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

Apply this formula for all numbers.

Step1:

LCM(191, 402) = 76782

GCD(191, 402) = ( 191 x 402 ) / 76782

= 191 / 402

= 191

Step2:

LCM(1, 646) = 646

GCD(1, 646) = ( 1 x 646 ) / 646

= 1 / 646

= 1

So, Greatest Common Divisor of 191, 402, 646 is 1
