Given numbers are 109, 646, 212

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

Apply this formula for all numbers.

Step1:

LCM(109, 646) = 70414

GCD(109, 646) = ( 109 x 646 ) / 70414

= 109 / 646

= 109

Step2:

LCM(1, 212) = 212

GCD(1, 212) = ( 1 x 212 ) / 212

= 1 / 212

= 1

So, Greatest Common Divisor of 109, 646, 212 is 1
