Given numbers are 245, 124, 432, 308

The list of prime factors of all numbers are

Prime factors of 245 are 5 x 7 x 7

Prime factors of 124 are 2 x 2 x 31

Prime factors of 432 are 2 x 2 x 2 x 2 x 3 x 3 x 3

Prime factors of 308 are 2 x 2 x 7 x 11

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

Given numbers are 245, 124, 432, 308

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

Apply this formula for all numbers.

Step1:

LCM(245, 124) = 30380

GCD(245, 124) = ( 245 x 124 ) / 30380

= 245 / 124

= 245

Step2:

LCM(1, 432) = 432

GCD(1, 432) = ( 1 x 432 ) / 432

= 1 / 432

= 1

Step3:

LCM(1, 308) = 308

GCD(1, 308) = ( 1 x 308 ) / 308

= 1 / 308

= 1

So, Greatest Common Divisor of 245, 124, 432, 308 is 1
