Question

find the largest number that divides 130 and 172leaving a reminder of 4

Answer 1

if we subtract 4 from the number we will get the number with which the remainder will be 4
130-4=126
172-4=168

Answer 2

Answer:

42

Step-by-step explanation:

Well, first of all subtract 4 from 130 and 172 which will be 126 and 168, then we would find the largest number which will divide both of the number or the HCF

this is how it will be done:

126 ) 168 ( 1

- 126

-----

42 ) 126 ( 3

- 126

-----

0

The last divisor which is 42 is the answer.

Hence, the the largest number that divides 130 and 172 or the HCF leaving a remainder of 4 is 42
