Given numbers are 868, 456, 660, 289

The list of prime factors of all numbers are

Prime factors of 868 are 2 x 2 x 7 x 31

Prime factors of 456 are 2 x 2 x 2 x 3 x 19

Prime factors of 660 are 2 x 2 x 3 x 5 x 11

Prime factors of 289 are 17 x 17

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

Given numbers are 868, 456, 660, 289

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

Apply this formula for all numbers.

Step1:

LCM(868, 456) = 98952

GCD(868, 456) = ( 868 x 456 ) / 98952

= 868 / 456

= 868

Step2:

LCM(4, 660) = 660

GCD(4, 660) = ( 4 x 660 ) / 660

= 4 / 660

= 4

Step3:

LCM(4, 289) = 1156

GCD(4, 289) = ( 4 x 289 ) / 1156

= 4 / 289

= 4

So, Greatest Common Divisor of 868, 456, 660, 289 is 1
