Given numbers are 455, 870, 192, 158

The list of prime factors of all numbers are

Prime factors of 455 are 5 x 7 x 13

Prime factors of 870 are 2 x 3 x 5 x 29

Prime factors of 192 are 2 x 2 x 2 x 2 x 2 x 2 x 3

Prime factors of 158 are 2 x 79

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

Given numbers are 455, 870, 192, 158

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

Apply this formula for all numbers.

Step1:

LCM(455, 870) = 79170

GCD(455, 870) = ( 455 x 870 ) / 79170

= 455 / 870

= 455

Step2:

LCM(5, 192) = 960

GCD(5, 192) = ( 5 x 192 ) / 960

= 5 / 192

= 5

Step3:

LCM(1, 158) = 158

GCD(1, 158) = ( 1 x 158 ) / 158

= 1 / 158

= 1

So, Greatest Common Divisor of 455, 870, 192, 158 is 1
