Given numbers are 220, 630, 743, 878

The list of prime factors of all numbers are

Prime factors of 220 are 2 x 2 x 5 x 11

Prime factors of 630 are 2 x 3 x 3 x 5 x 7

Prime factors of 743 are 743

Prime factors of 878 are 2 x 439

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

Given numbers are 220, 630, 743, 878

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

Apply this formula for all numbers.

Step1:

LCM(220, 630) = 13860

GCD(220, 630) = ( 220 x 630 ) / 13860

= 220 / 630

= 220

Step2:

LCM(10, 743) = 7430

GCD(10, 743) = ( 10 x 743 ) / 7430

= 10 / 743

= 10

Step3:

LCM(1, 878) = 878

GCD(1, 878) = ( 1 x 878 ) / 878

= 1 / 878

= 1

So, Greatest Common Divisor of 220, 630, 743, 878 is 1
