Given numbers are 213, 755, 864, 491

The list of prime factors of all numbers are

Prime factors of 213 are 3 x 71

Prime factors of 755 are 5 x 151

Prime factors of 864 are 2 x 2 x 2 x 2 x 2 x 3 x 3 x 3

Prime factors of 491 are 491

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

Given numbers are 213, 755, 864, 491

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

Apply this formula for all numbers.

Step1:

LCM(213, 755) = 160815

GCD(213, 755) = ( 213 x 755 ) / 160815

= 213 / 755

= 213

Step2:

LCM(1, 864) = 864

GCD(1, 864) = ( 1 x 864 ) / 864

= 1 / 864

= 1

Step3:

LCM(1, 491) = 491

GCD(1, 491) = ( 1 x 491 ) / 491

= 1 / 491

= 1

So, Greatest Common Divisor of 213, 755, 864, 491 is 1
