Given numbers are 390, 860, 245, 223

The list of prime factors of all numbers are

Prime factors of 390 are 2 x 3 x 5 x 13

Prime factors of 860 are 2 x 2 x 5 x 43

Prime factors of 245 are 5 x 7 x 7

Prime factors of 223 are 223

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

Given numbers are 390, 860, 245, 223

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

Apply this formula for all numbers.

Step1:

LCM(390, 860) = 33540

GCD(390, 860) = ( 390 x 860 ) / 33540

= 390 / 860

= 390

Step2:

LCM(10, 245) = 490

GCD(10, 245) = ( 10 x 245 ) / 490

= 10 / 245

= 10

Step3:

LCM(5, 223) = 1115

GCD(5, 223) = ( 5 x 223 ) / 1115

= 5 / 223

= 5

So, Greatest Common Divisor of 390, 860, 245, 223 is 1
