Multiples of 12 are 12, 24, 36, 48, etc. Factors of 36 are 1, 2, 3, 4, 6, 9, 12, 18, 36. Numbers that are multiples of 12 and factors of 36 are 12 and 36.
1, 2, 3, 4, 6 and 12
Factors for 36 are: 1, 2, 3, 4, 6, 9, 12, 18, 36 Apart from 4, the only other factor of 36 which is a multiple of 4 is 12 (Excluding 36)
Four and three share eight common multiples between 1 and 100:12, 24, 36, 48, 60, 72, 84, 96 Remamber that zero is a multiple of all numbers.
There are 5 multiples of 9. There are 4 multiples of 12. There is 1 number that is a multiple of both, 36.
The lowest common factor between two numbers is the multiple apart from 1 that the two numbers share which is the lowest. For example: The numbers 36 and 45. Multiples of 36 are {1,2,3,4,6,9,12,24,36} Multiples of 45 are {1,3,5,9,15,45} It is evident that their shared multiples are 1,3,9. But we exclude 1, therefore 3 is the LCM (or LCF)
Two numbers
Squares numbers are positive numbers. So that the square numbers less than 100 are 1, 4, 9, 16, 25, 36, 49, 64, and 81, and only 16 and 64 are multiples of 8. Thus, Greta picked 16, and 64.
33 multiples of 3 plus 12 multiples of 8 minus 4 multiples of both. 41%
3 and all of its multiples.
Six numbers
The HCF of both numbers is 1
