It is 1
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
The number that goes into both 18 and 27 is their greatest common divisor (GCD), which is 9. Both 18 and 27 can be evenly divided by 9. Additionally, the factors of both numbers include 1, 3, and 9.
33*9=273*11=33
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
6 and 9 both go into 54.
33*9=273*11=33
The number that goes into both 9 and 36 is their greatest common divisor (GCD), which is 9. This means 9 divides both numbers without leaving a remainder. Additionally, other common divisors include 1 and 3, but the largest one is 9.
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
