Given numbers are 223, 688, 910, 861

The list of prime factors of all numbers are

Prime factors of 223 are 223

Prime factors of 688 are 2 x 2 x 2 x 2 x 43

Prime factors of 910 are 2 x 5 x 7 x 13

Prime factors of 861 are 3 x 7 x 41

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

Given numbers are 223, 688, 910, 861

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

Apply this formula for all numbers.

Step1:

LCM(223, 688) = 153424

GCD(223, 688) = ( 223 x 688 ) / 153424

= 223 / 688

= 223

Step2:

LCM(1, 910) = 910

GCD(1, 910) = ( 1 x 910 ) / 910

= 1 / 910

= 1

Step3:

LCM(1, 861) = 861

GCD(1, 861) = ( 1 x 861 ) / 861

= 1 / 861

= 1

So, Greatest Common Divisor of 223, 688, 910, 861 is 1
