Given numbers are 217, 118, 816, 890

The list of prime factors of all numbers are

Prime factors of 217 are 7 x 31

Prime factors of 118 are 2 x 59

Prime factors of 816 are 2 x 2 x 2 x 2 x 3 x 17

Prime factors of 890 are 2 x 5 x 89

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

Given numbers are 217, 118, 816, 890

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

Apply this formula for all numbers.

Step1:

LCM(217, 118) = 25606

GCD(217, 118) = ( 217 x 118 ) / 25606

= 217 / 118

= 217

Step2:

LCM(1, 816) = 816

GCD(1, 816) = ( 1 x 816 ) / 816

= 1 / 816

= 1

Step3:

LCM(1, 890) = 890

GCD(1, 890) = ( 1 x 890 ) / 890

= 1 / 890

= 1

So, Greatest Common Divisor of 217, 118, 816, 890 is 1
