2 and 12
13 can only be dived equally by 1 and 13
No integer other than 1 does. Numbers like this are said to be co-prime.
180 / 15 = 12
13x9= 117 13 is prime so you don't continue with 13 because nothing goes into it equally. Then you continue with 9, and obviously 3 goes into 9 three times. (3x3=9) Now, since nothing goes evenly into three, we stop our factor tree. (:
It is: 1
The number that goes into both 12 and 72 equally is 12. This is because 72 divided by 12 equals 6, so 12 is a common divisor of both numbers.
Yes and it is 1
2 and 12
Nothing goes into 13 equally. No 2 whole numbers multiplied together can make it. Only 6+7=13.
1, 3, 9, 13, 39, 117.
What goes in 100 equally
1, 7, 11, 13, 77, 91, 143, 1001.
13 can only be dived equally by 1 and 13
No integer other than 1 does. Numbers like this are said to be co-prime.
No. It goes in 10 times, with 2 left over. 10 times 12 is 120, plus 2 is 122.
That number is 1.
