Given numbers are 432, 448, 655, 245

The list of prime factors of all numbers are

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

Prime factors of 448 are 2 x 2 x 2 x 2 x 2 x 2 x 7

Prime factors of 655 are 5 x 131

Prime factors of 245 are 5 x 7 x 7

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

Given numbers are 432, 448, 655, 245

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

Apply this formula for all numbers.

Step1:

LCM(432, 448) = 12096

GCD(432, 448) = ( 432 x 448 ) / 12096

= 432 / 448

= 432

Step2:

LCM(16, 655) = 10480

GCD(16, 655) = ( 16 x 655 ) / 10480

= 16 / 655

= 16

Step3:

LCM(1, 245) = 245

GCD(1, 245) = ( 1 x 245 ) / 245

= 1 / 245

= 1

So, Greatest Common Divisor of 432, 448, 655, 245 is 1
