Given numbers are 217, 411, 400, 864

The list of prime factors of all numbers are

Prime factors of 217 are 7 x 31

Prime factors of 411 are 3 x 137

Prime factors of 400 are 2 x 2 x 2 x 2 x 5 x 5

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

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

Given numbers are 217, 411, 400, 864

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

Apply this formula for all numbers.

Step1:

LCM(217, 411) = 89187

GCD(217, 411) = ( 217 x 411 ) / 89187

= 217 / 411

= 217

Step2:

LCM(1, 400) = 400

GCD(1, 400) = ( 1 x 400 ) / 400

= 1 / 400

= 1

Step3:

LCM(1, 864) = 864

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

= 1 / 864

= 1

So, Greatest Common Divisor of 217, 411, 400, 864 is 1
