Given numbers are 530, 346, 245, 220

The list of prime factors of all numbers are

Prime factors of 530 are 2 x 5 x 53

Prime factors of 346 are 2 x 173

Prime factors of 245 are 5 x 7 x 7

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

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

Given numbers are 530, 346, 245, 220

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

Apply this formula for all numbers.

Step1:

LCM(530, 346) = 91690

GCD(530, 346) = ( 530 x 346 ) / 91690

= 530 / 346

= 530

Step2:

LCM(2, 245) = 490

GCD(2, 245) = ( 2 x 245 ) / 490

= 2 / 245

= 2

Step3:

LCM(1, 220) = 220

GCD(1, 220) = ( 1 x 220 ) / 220

= 1 / 220

= 1

So, Greatest Common Divisor of 530, 346, 245, 220 is 1
