Given numbers are 448, 156, 490, 129

The list of prime factors of all numbers are

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

Prime factors of 156 are 2 x 2 x 3 x 13

Prime factors of 490 are 2 x 5 x 7 x 7

Prime factors of 129 are 3 x 43

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

Given numbers are 448, 156, 490, 129

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

Apply this formula for all numbers.

Step1:

LCM(448, 156) = 17472

GCD(448, 156) = ( 448 x 156 ) / 17472

= 448 / 156

= 448

Step2:

LCM(4, 490) = 980

GCD(4, 490) = ( 4 x 490 ) / 980

= 4 / 490

= 4

Step3:

LCM(2, 129) = 258

GCD(2, 129) = ( 2 x 129 ) / 258

= 2 / 129

= 2

So, Greatest Common Divisor of 448, 156, 490, 129 is 1
