Given numbers are 497, 156, 448, 145

The list of prime factors of all numbers are

Prime factors of 497 are 7 x 71

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

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

Prime factors of 145 are 5 x 29

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

Given numbers are 497, 156, 448, 145

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

Apply this formula for all numbers.

Step1:

LCM(497, 156) = 77532

GCD(497, 156) = ( 497 x 156 ) / 77532

= 497 / 156

= 497

Step2:

LCM(1, 448) = 448

GCD(1, 448) = ( 1 x 448 ) / 448

= 1 / 448

= 1

Step3:

LCM(1, 145) = 145

GCD(1, 145) = ( 1 x 145 ) / 145

= 1 / 145

= 1

So, Greatest Common Divisor of 497, 156, 448, 145 is 1
