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 is the hcf and LCM of 14 and 30?

hcf(14, 30) = 2 lcm(14, 30) = 210 14 = 2 x 7 30 = 2 x 3 x 5 hcf = 2 lcm = 2 x 3 x 5 x 7 = 210

What is the hcf of 210 and 308?

The highest common factor (HCF) of 210 and 308 is the largest positive integer that divides both 210 and 308 without leaving a remainder. To find the HCF, you can use the Euclidean algorithm or prime factorization method. By prime factorizing 210 (2 x 3 x 5 x 7) and 308 (2 x 2 x 7 x 11), you can identify the common prime factors, which are 2 and 7. Therefore, the HCF of 210 and 308 is 14.

What is the HCF of 210 and 504?

The Highest Common Factor (HCF) of two numbers is the largest positive integer that divides both numbers without leaving a remainder. To find the HCF of 210 and 504, you can use the Euclidean algorithm or prime factorization method. In this case, the prime factorization of 210 is 2 x 3 x 5 x 7, and the prime factorization of 504 is 2^3 x 3^2 x 7. To find the HCF, you take the common prime factors with the lowest exponents, which are 2 x 3 x 7 = 42. Therefore, the HCF of 210 and 504 is 42.

What is the GCF of 140 and 210?

The Greatest Common Factor (GCF) of 210 and 140 is 70.

What is the ratio of 210 and 140?

Oh, dude, the ratio of 210 to 140 is like 3:2. It's just a fancy way of saying if you have 210 things, you'd have 3 times as many as if you had 140 things. But like, who's counting, right?

What is the HCF of 210 and 165?

The Highest Common Factor (HCF) of 210 and 165 is the largest positive integer that divides both numbers without leaving a remainder. To find the HCF, you can use the Euclidean algorithm, which involves dividing the larger number by the smaller number and then using the remainder as the new divisor until the remainder becomes zero. In this case, the HCF of 210 and 165 is 15.
