Given numbers are 217, 975, 871, 918

The list of prime factors of all numbers are

Prime factors of 217 are 7 x 31

Prime factors of 975 are 3 x 5 x 5 x 13

Prime factors of 871 are 13 x 67

Prime factors of 918 are 2 x 3 x 3 x 3 x 17

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

Given numbers are 217, 975, 871, 918

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

Apply this formula for all numbers.

Step1:

LCM(217, 975) = 211575

GCD(217, 975) = ( 217 x 975 ) / 211575

= 217 / 975

= 217

Step2:

LCM(1, 871) = 871

GCD(1, 871) = ( 1 x 871 ) / 871

= 1 / 871

= 1

Step3:

LCM(1, 918) = 918

GCD(1, 918) = ( 1 x 918 ) / 918

= 1 / 918

= 1

So, Greatest Common Divisor of 217, 975, 871, 918 is 1
