One two digit number that is not prime and is not a multiple of 2, 3, or 5 is 49. Another such number is 91.
The least common multiple of the numbers 49 and 99 is 4,851.
The least common multiple of the numbers 4 and 49 is 196.
The least common multiple of the numbers 30 and 49 is 1,470.
You have seven different digits (symbols) to choose from, so you can form seven different one digit numbers and 7×7=72=49 different two digit numbers.
There is not a least common multiple of a single number, such as 49, because there cannot be a least common multiple without two or more numbers to compare. Common multiples are multiples that the numbers being compared have in common. The least common multiple is the smallest multiple that all the numbers being compared have in common. Examples: The least common multiple of 3 and 49 is 147. The least common multiple of 14 and 49 is 98. The least common multiple of 49 and 196 is 196.
The least common multiple of the numbers 6 and 49 is 294.Their product.
The least common multiple of the numbers 21, 48 and 49 is 2,352.
7*7 = 49 numbers.7*7 = 49 numbers.7*7 = 49 numbers.7*7 = 49 numbers.
There are 49 3-digit numbers - from 108 to 990 inclusive.
It is not possible to give a sensible answer to this question. The least common multiple (LCM) refers to a multiple that is COMMON to two or more numbers. You have only one number in the question!
