Only 1 goes in to 9 and 11 as a whole number. Technically any number can go into any number.
9
Besides 1, the number 3 goes into both 9 and 42. 9/3=3 and 42/3=14
33*9=273*11=33
6 and 9 both go into 54.
Only 1 goes in to 9 and 11 as a whole number. Technically any number can go into any number.
The number that goes into both 9 and 5 is 1. This is because 1 is a factor of every integer, including 9 and 5. In other words, both 9 and 5 can be divided evenly by 1.
1, 3 and 9
9
That number is 9.
The only common factor (number that goes into both) of 47 and 9 is ' 1 '.
Besides 1, the number 3 goes into both 9 and 42. 9/3=3 and 42/3=14
33*9=273*11=33
6 and 9 both go into 54.
16 and 9 are coprime so that the only number going into both is 1.
Little Mathematical trick. If the digits in a number add up to 3 or a multiple of 3 then that number is divisible by 3. If the digits of a number add up to 9 or a multiple of 9 then that number is divisible by 9. 2 + 9 + 7 = 18 ........which is a multiple of both 3 and 9. Lets start with 3 297 ÷ 3 = 99 (9 + 9 = 18 so we can divide again by 3 and/or9) 99 ÷ 3 = 33 (3 + 3 = 6 so we can divide by 3) 33 ÷ 3 = 11 (11 is a prime number so no more factors. The prime factors of 297 are 33 and 11. The factors of 297 are : 297, 99, 33, 27, 11, 9, 3 and 1
3 and 1 will go into both number evenly leaving no remainders.
