Given numbers are 170, 655, 448, 154

The list of prime factors of all numbers are

Prime factors of 170 are 2 x 5 x 17

Prime factors of 655 are 5 x 131

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

Prime factors of 154 are 2 x 7 x 11

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

Given numbers are 170, 655, 448, 154

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

Apply this formula for all numbers.

Step1:

LCM(170, 655) = 22270

GCD(170, 655) = ( 170 x 655 ) / 22270

= 170 / 655

= 170

Step2:

LCM(5, 448) = 2240

GCD(5, 448) = ( 5 x 448 ) / 2240

= 5 / 448

= 5

Step3:

LCM(1, 154) = 154

GCD(1, 154) = ( 1 x 154 ) / 154

= 1 / 154

= 1

So, Greatest Common Divisor of 170, 655, 448, 154 is 1
