Infinitely many.
There are 5 multiples of 9. There are 4 multiples of 12. There is 1 number that is a multiple of both, 36.
Multiples of 9
there are too many! like 9, 18, 27, 36,...basially, all the multiples of nine are also multiples of 3.
They are all multiples of 3.
Both digits are successive counting numbers.
The least common multiples of the number 6 and 9 is 3.
Multiples are formed by multiplying a number by successive counting numbers. The multiples of 9 are 9, 18, 27, 36, 45, 54, 63, 72, 81, 90, 99 and so on.
There are an infinite number of multiples of 9
Well, honey, to find the number of 4-digit multiples of 9, you just need to divide the largest 4-digit multiple of 9 (9999) by 9 and subtract the smallest 4-digit multiple of 9 (1008) divided by 9. So, 9999 ÷ 9 - 1008 ÷ 9 = 1111 - 112 = 999. That's right, there are 999 4-digit numbers that are multiples of 9.
Multiples are just numbers that can be multiplied together to find the given number. So: Multiples of 9: 1,3,9 Multiples of 18: 1,2,3,6,9,18 Common Multiples of 9 & 18: 1,3,9
To find the LCM of a number in this case 6 and 9 you find all of their multiples that they share in this caseThe multiples of 6 are 2,3,6
There are infinitely many multiples of 9 and it is not possible to add them all.
