Given numbers are 871, 448, 155, 408

The list of prime factors of all numbers are

Prime factors of 871 are 13 x 67

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

Prime factors of 155 are 5 x 31

Prime factors of 408 are 2 x 2 x 2 x 3 x 17

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

Given numbers are 871, 448, 155, 408

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

Apply this formula for all numbers.

Step1:

LCM(871, 448) = 390208

GCD(871, 448) = ( 871 x 448 ) / 390208

= 871 / 448

= 871

Step2:

LCM(1, 155) = 155

GCD(1, 155) = ( 1 x 155 ) / 155

= 1 / 155

= 1

Step3:

LCM(1, 408) = 408

GCD(1, 408) = ( 1 x 408 ) / 408

= 1 / 408

= 1

So, Greatest Common Divisor of 871, 448, 155, 408 is 1
