Given numbers are 213, 240, 113, 644

The list of prime factors of all numbers are

Prime factors of 213 are 3 x 71

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

Prime factors of 113 are 113

Prime factors of 644 are 2 x 2 x 7 x 23

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

Given numbers are 213, 240, 113, 644

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

Apply this formula for all numbers.

Step1:

LCM(213, 240) = 17040

GCD(213, 240) = ( 213 x 240 ) / 17040

= 213 / 240

= 213

Step2:

LCM(3, 113) = 339

GCD(3, 113) = ( 3 x 113 ) / 339

= 3 / 113

= 3

Step3:

LCM(1, 644) = 644

GCD(1, 644) = ( 1 x 644 ) / 644

= 1 / 644

= 1

So, Greatest Common Divisor of 213, 240, 113, 644 is 1
