120 is the LCM
120 and all its multiples.
Sum of the first 15 positive integers is 15*(15+1)/2 = 120 Sum of the first 15 multiples of 8 is 8*120 = 960
Since 8 is a multiple of 2 and 4, all multiples of 8 are also multiples of both of them. Thus, Jose and maria are both correct.
Both of them.
The Least Common Multiple (LCM) for 8 10 15 is 120.
The multiples of 2 between 7 and 15 are 8, 10, 12, and 14.
Common denominators of 8 and 15 are 120 and all its multiples.
120
40 and all its multiples...
Any multiple of 15.
The first multiples of 15 are 15, 30, 45, 60, 75, and so on. The first multiples of 4 are 4, 8, 12, 16, 20, and so forth. Multiples are numbers that can be divided evenly by another number.
Since both 3 and 5 are prime numbers, only numbers that are multiples of its product are the numbers that are divisible by both. 15 is the LCM of 3 and 5 and hence all multiples of 15 are divisible by both 3 and 5
