What is the LCM for 40 and 100?
factor both numbers factor 40 into [2 2 2 5] or [2^3 * 5] factor 100 into [2 2 5 5] or [2² * 5²] LCM is the highest power of each common factor 2^3 * 5² = 8 * 25 = 200 ◄
What two numbers have 2 3 and 5 as a factor?
30 and 60
What are 2 numbers that have the greatest common factor of 1?
3 and 5.
What are the prime factor out of 3 2 5?
All of them are prime numbers
What numbers have 2 3 and 5 as a factor?
Any multiple of 30 has these factors.
What is the greatest common factor of 3 5 and 8?
The greatest common factor of several numbers cannot be larger than the greatest common factor of any pair of the numbers. If you realize that the greatest common factor of 3 and 5 is 1, the greatest common factor of all the numbers must be 1. Another way to determine the greatest common factor is to find all the factors of the numbers and compare them. The factors of 3 are 1 and 3. The factors of 5 are 1 and 5. The factors of 8 are 1, 2, 4, and 8. The factors of 10 are 1, 2, 5, and 10. The only common factor is 1. Therefore, the greatest common factor is 1. The greatest common factor can also be calculated by identifying the common prime factors and multiplying them together. The prime factor of 3 is 3. The prime factor of 5 is 5. The prime factors of 8 are 2, 2, and 2. The prime factors of 10 are 2 and 5. There are no prime factors in common, so the greatest common factor is 1.
Which numbers appear on the bottom row for a factor tree of 30?
5, 3, and 2.
What is the GCF of 102 and 50?
factor out both numbers to get 102=2*3*17 50=2*5*5 the GCF is 2
What is the least common multiple of 2 3 5 and 9?
To determine the least common multiple of more than two numbers, determine the prime factors of all numbers. Then, determine the prime factors they have in common with at least one of the other numbers and the ones that are not in common. The prime factor of 2 is 2. The prime factor of 3 is 3. The prime factor of 5 is 5. The prime factors of 9 are 3 and 3. The prime factor 3 is a factor in common in one pair. Multiply all the factors together and divide by any that were in common with the other numbers. Therefore, the least common multiple is 2 x 3 x 5 x 9 ÷ 3 = 90
Do all numbers that have 13 as a factor also have 5 as a factor?
Not AllTo find out if all numbers that have 5 as a factor have 2 as a factor, you can list the multiples of each. 5's multiples are 5, 10, 15, 20...2's multiples are 2, 4, 6, 8, 10, 12, 14, 16, 18, 20...5 and 15 are multiples of 5, but not 2, so all numbers that have 5 as a factor DO NOT have 2 as a factor.It is not really necessary to write that all out because the fact that 5 is an odd number and 2 is only a factor of even numbers indicates that all numbers that have 5 as a factor would not have 2 as a factor. Only the multiples of 5 that are even have 2 as a factor also.
What is the GCF of 23 x 32 x 5?
2^3 x 3^2 x 5 = 360 You need at least two numbers to find a GCF.
What numbers have prime factors of 2, 3, 5, and 11 that they share. What is the greatest common factor of the two numbers?
330
