The only number is 1. But if you are looking for number that they each go into, the smallest number is 210.
These numbers go evenly into 415: 1, 5, 83, 415.
The only number which will go evenly into all of them is 1.
1 and 5.
All composite numbers can be expressed as unique products of prime numbers. This is accomplished by dividing the original number and its factors by prime numbers until all the factors are prime. A factor tree can help you visualize this. Example: 210 210 Divide by two. 105,2 Divide by three. 35,3,2 Divide by five. 7,5,3,2 Stop. All the factors are prime. 2 x 3 x 5 x 7 = 210 That's the prime factorization of 210.
The numbers that go into 45 are 1, 3, 5, 9, 15, and 45.
All numbers that go into 130 are 1, 2, 5, 10, 13, 26, 65, and 130.
45
2 and 5
all you have to do is find 2 factors that equals 25 which is 5 and 5 and then your done basically because 5 are prime numbers, they have no fators. there are other numbers you can use to but 5 and 5 is one way.
1, 5, 13, 65.
2, 3 and 5
1, 5, 13, 65.
By making a number tree that could have as many as 1,000,000 combos.
2 x 5 x 5 = 50
