Given numbers are 918, 820, 863, 221

The list of prime factors of all numbers are

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

Prime factors of 820 are 2 x 2 x 5 x 41

Prime factors of 863 are 863

Prime factors of 221 are 13 x 17

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

Given numbers are 918, 820, 863, 221

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

Apply this formula for all numbers.

Step1:

LCM(918, 820) = 376380

GCD(918, 820) = ( 918 x 820 ) / 376380

= 918 / 820

= 918

Step2:

LCM(2, 863) = 1726

GCD(2, 863) = ( 2 x 863 ) / 1726

= 2 / 863

= 2

Step3:

LCM(1, 221) = 221

GCD(1, 221) = ( 1 x 221 ) / 221

= 1 / 221

= 1

So, Greatest Common Divisor of 918, 820, 863, 221 is 1
