One of them is 2 and 36
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.
1, 3 and 9
18 27 36 45 54 63 72 81 90
The numbers 1, 3 and 9 all go into both 72 and 171.
To find how many ways 72 can be set up in rows equally, we need to determine the divisors of 72. The divisors of 72 are the numbers that can evenly divide 72, which are 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36, and 72. In total, there are 12 divisors, meaning there are 12 different ways to set up 72 in rows equally.
What goes in 100 equally
2,3,5,7,11,13,17,19,23,29,31,37,41,43,47,53,59,61,67,71 that's as far up as it goes because 72 is a composite number not a prime number!
1, 3 and 9 will go into both numbers evenly
Nothing goes into 13 equally. No 2 whole numbers multiplied together can make it. Only 6+7=13.
The number that goes into 19 and 100 equally is 1. This is because any number divided by 1 is equal to the original number. In this case, both 19 and 100 divided by 1 result in the original numbers, making 1 the common factor that divides into both numbers equally.
83 is a prime number. Therefore, the only numbers that divide equally into it are itself and 1.
No integer other than 1 does. Numbers like this are said to be co-prime.
