Given numbers are 213, 171, 646

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

Apply this formula for all numbers.

Step1:

LCM(213, 171) = 12141

GCD(213, 171) = ( 213 x 171 ) / 12141

= 213 / 171

= 213

Step2:

LCM(3, 646) = 1938

GCD(3, 646) = ( 3 x 646 ) / 1938

= 3 / 646

= 3

So, Greatest Common Divisor of 213, 171, 646 is 1
