Given numbers are 213, 206, 240, 421

The list of prime factors of all numbers are

Prime factors of 213 are 3 x 71

Prime factors of 206 are 2 x 103

Prime factors of 240 are 2 x 2 x 2 x 2 x 3 x 5

Prime factors of 421 are 421

The above numbers do not have any common prime factor. So GCD is 1

Given numbers are 213, 206, 240, 421

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

Apply this formula for all numbers.

Step1:

LCM(213, 206) = 43878

GCD(213, 206) = ( 213 x 206 ) / 43878

= 213 / 206

= 213

Step2:

LCM(1, 240) = 240

GCD(1, 240) = ( 1 x 240 ) / 240

= 1 / 240

= 1

Step3:

LCM(1, 421) = 421

GCD(1, 421) = ( 1 x 421 ) / 421

= 1 / 421

= 1

So, Greatest Common Divisor of 213, 206, 240, 421 is 1
