What is the common multiples of 22 and 44? I think it is 1,2,11,22
It is always useful to know about factors and multiples.
3, 6, 12 and 24
Factors go into numbers, numbers go into multiples.
22 is a multiple of 11. 22 is a factor of 44.
Common factors: 1 and 2 Common multiples: Any multiple of 132
Factors create multiples, multiples break down into factors.
1, 2, 4, 8, 11, 22, 44, 88
As a product of its prime factors: 2*2*3*5 = 60 or as 22*3*5 = 60
the factors and multiples of 396 are 1,2,3,4,6,9,11,12,18,22,33,36,44,66,99,132,198,396
What is the common multiples of 22 and 44? I think it is 1,2,11,22
Factors: 1,2,3,6 Multiples: 6,12,18,24 and so on.
Factors go into numbers, numbers go into multiples. Divisibility shows what factors come out of what multiples.
The factors of 36 are: 1, 2, 3, 4, 6, 9, 12, 18, 36. Thus the multiples of 2 which are not factors of 36 are: 8, 10, 14, 16, 20, 22, 24, 26, 28, 30, 32, 34, 38, 40, 42, ... (all multiples of 2 greater than 36 are not factors of 36).
The factors of 2 are 1, 2, 11 and 22. None of them are multiples of 8.
The multiples of 3 between 1 and 22 are: 3,6,9,12,15,18,21.
