Is 210 a composite number and why?
Yes, because it has more than two factors.
What is the lcm of 42 and 30?
Start by factoring each of the numbers. Then eliminate duplicate factors, and multiply together whatever factors are left. 42=2x3X7 30=2x3x5 Since the 2 and 3 are duplicated, eliminate the duplications, and multiply 2X3X5X7=210. Answer: 210
What number has more than 10 factors?
Well, honey, any number that is a square of a prime number will have more than 10 factors. So, for example, 16 is the square of 4, a prime number, and it has 10 factors. But if you want more than 10 factors, you gotta step it up to numbers like 36, which is the square of 6, and has 18 factors. Math can be sassy too, you know!
How do you find out what is the smallest number with eleven factors?
Prime numbers, raised to a power, have one more factor than their exponents. The smallest prime number is 2. 210 has eleven factors. 210 = 1024
Is it possible to find different ways to multiply the same number of factors of 120 180 210?
Yes.
What is 21 multiply by 10?
21 multiply by 10 = 210
How do you find the smallest number with 11 factors?
Prime numbers, raised to a power, have one more factor than their exponents. The smallest prime number is 2. 210 has eleven factors. 210 = 1024
What numbers do you add to get 11 and multiply to get 210?
221
Find the HCF for these sets of numbers 30, 210 and 700?
To find the highest common factor (HCF) of 30, 210, and 700, you can use the prime factorization method. Prime Factorization: Prime factorize each number: 30 = 2 * 3 * 5 210 = 2 * 3 * 5 * 7 700 = 2^2 * 5^2 * 7 Identify Common Prime Factors: Identify the common prime factors among the numbers: 2, 3, 5, and 7. Multiply Common Prime Factors: Multiply the common prime factors: 2 * 3 * 5 * 7 = 210 Therefore, the HCF of 30, 210, and 700 is 210.
What number is 210 more than 110?
210 + 110 = 320
Least common denominator of 6 and 35?
6 and 35 have no common factors, so just multiply both numbers.
What is a factor of 210 and 231?
The factors of 231 are 1,3,7,11,21,33,77 and 231 The factors of 210 are 1,2,3,5,6,7,10,14,15,21,30,35,42,70,105 and 210 The common factors are therefore 1,3,7 and 21
