What is the least common multiple of 210 and 315 and how?
It is: 630 by multiplying the highest prime factors of both numbers
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 is the highest common factor in 210 and 147?
Prime factors of 210 = 2 x 3 x 5 x 7Prime factors of 147 = 3 x 7 x 7Common factors = 3 x 7 so the highest common factor is 21.
What is the highest prime factor of 210?
Seven is the highest prime factor. The prime factors for 210 are: 2 x 3 x 5 x 7
What is the highest common multiple of 210 and 147 using prime numbers?
There is no such thing as a 'highest common multiple', but the least common multiple or LCM can be found using prime numbers. The LCM of the given numbers is the product of all different prime factors to their greatest power. If there are no exponents, the greatest power of the prime factors is 1 and each different prime factor is used in the multiplication:prime factors of 210 are 2 x 3 x 5 x 7;prime factors of 147 are 3 x 72;the LCM of 210 and 147 is 2 x 3 x 5 x 72 = 1470
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.
Are 210 and 21 relatively prime?
No. They have many common factors, not just 1.
What is the least common multiple of 5 14 and 30?
The LCM of 5, 14, and 30 is 210 Answer: You calculate the prime factors for each number, write them down, then use each prime number once (or in the highest power in which it appears in any of the factors) in the result.
What are the prime factors of 210?
The prime factors are: 2 3 5 72, 3, 5 and 7
Why is it that the least common multiple of 10 and 21 is 210?
Because the prime factors of 10 are 2 and 5, the prime factors of 21 are 3 and 7 So multiplying all the higest prime factors: 2*5*3*7 = 210
What prime numbers equal 210?
The prime factors of 210 are 2x3x5x7.
How do you work out the hcf of 210 and 385?
Prime factors of 210 are: 2, 3, 5 and 7 Prime factors of 385 are: 5,7 and 11 Common factors are: 5 and 7 and so 5*7 = 35 which is the hcf
