The HCF of both numbers is 6
The HCF of both numbers is 6
The number is 18 because 42+18 = 60
The number 1 goes into both 17 and 42. In this instance, one goes into each number exact the same number of times as the original number like 17 or 42.
There is an infinite number of common multiples for 18 and 42. A common multiple of any two numbers is any number into which each of two or more numbers can be divided evenly (zero remainder).
The number is 18 because 2*(18)+6 = 42
An infinite number of of multiples of 42 can be divided by 42.

Besides 1, the number 3 goes into both 9 and 42. 9/3=3 and 42/3=14
Thirty 42 - 18 = 24 24 / 2 = 12 18 + 12 = 30 42 - 12 = 30
It is: 4.2
