A prime number has no factors other than 1 and itself. Each multiple of fifteen includes 3, 5, and 15 among its factors.
What numbers have 5 and 3 as factors?
All multiples of 15 (15, 30, 45, 60, etc.) have 5 and 3 as factors.
What is the Least common multiple of 15 and 70?
The LCM is the product of the two divided by the GCF Factors of 15 are [3 5] Factors of 70 are [2 5 7] Common factor is [5] (15 * 70) / 5 = 210 ■
What is a product multiplication?
The product is the result of multiplying two or more numbers.In the calculation 3 x 5 = 153 is the multiplicand and 5 is the multiplier. Both of them are factors, and 15 is the product. 15 is also referred to as a multiple of the numbers - 15 is a multiple of 3, and 15 is a multiple of 5.

What are factors and multiples of 12?
if you find the prime factors it makes the number easier to multiple. first make prime factor trees for each of the numbers. i did 18x15. 18 could have 3, 3 and 2 and 15 could have 3 and 5. then the sum could be: 5x2=10x3=30x3=90x3=270 hope this helps. if you are not sure, look up prime factor trees first.
What is the least common multiple of 4 5 15 and 18?
factor the numbers... factors of each: 4 = 2,2 5 = 1,5 15= 3,5 18= 3,6 now multiply each of the factors once per occurrence: 2*1*5*3*6 equals: 180 this is the LCM.
What is the least common multiple of 14 and 15?
