What is the square root of 210 simplified?
210 = 2*105 = 2*3*35 = 2*3*5*7. To simplify sqrt(210) you need a pair of factors to form a square. You can then take out the square root, which will be a whole number. Since 210 has no pair of factors, sqrt(210) cannot be simplified.
Is the HCF of 140 and 210 2?
No. The prime factors of 140 are 2,2,5 and 7 The prime factors of 210 are 2,3,5 and 7 The common prime factors are 2,5 and 7 Thus the HCF is 2x5x7, or 70.
What are the factors and prime factors of 210?
210 is a composite number because it has factors other than 1 and itself. It is not a prime number.The 16 factors of 210 are 1, 2, 3, 5, 6, 7, 10, 14, 15, 21, 30, 35, 42, 70, 105, and 210.The factor pairs of 210 are 1 x 210, 2 x 105, 3 x 70, 5 x 42, 6 x 35, 7 x 30, 10 x 21, and 14 x 15.The proper factors of 210 are 1, 2, 3, 5, 6, 7, 10, 14, 15, 21, 30, 35, 41, 70, and 105 or,if the definition you are using excludes 1, they are 2, 3, 5, 6, 7, 10, 14, 15, 21, 30, 35, 41, 70, and 105.The prime factors of 210 are 2, 3, 5, and 7.The distinct prime factors (listing each prime factor only once) of 210 are also 2, 3, 5, and 7.The prime factorization of 210 is 2 x 3 x 5 x 7.NOTE: There cannot be common factors, a greatest common factor, or a least common multiple because "common" refers to factors or multiples that two or more numbers have in common. 1, 2, 3, 5, 6, 7, 10, 14, 15, 21, 30, 35, 42, 70, 105 and 210.
How do you find the greatest common factor of 210 and 308?
* One method is to factor each number into prime factors, and see what factors they have in common. 210 = 2x105 = 2x5x21 = 2x5x3x7, or 2x3x5x7. 308 = 2x154 = 2x2x77 = 2x2x7x11. The GCF is 2x7 = 14. * Another method (more efficient, especially for larger numbers) is Euclid's algorithm. In this case for example, the greatest common factor of 308 and 210 is the same as the greatest common factor of 210 and 98. This latter number is the remainder of the division of 308 by 210. Continue until one of the numbers is zero. In that case, the other one is the greatest common factor. 308/210 = 1, remainder 98 210/98 = 2, remainder 14 98/14 = 7, remainder 0. The previous remainder (14) is the GCF.
What is the sum of all integers from 1 to 20?

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
How do you know when you have found all the prime factors?
If all the factors are prime numbers and they total the original number, you have found them all. All composite numbers can be expressed as unique products of prime numbers. This is accomplished by dividing the original number and its factors by prime numbers until all the factors are prime. A factor tree can help you visualize this. Example: 210 210 Divide by two. 105,2 Divide by three. 35,3,2 Divide by five. 7,5,3,2 Stop. All the factors are prime. 2 x 3 x 5 x 7 = 210 That's the prime factorization of 210.
