The GCF is 7.
The HCF is 7.
To calculate the Highest Common Factor (HCF) of 28, 14, and 21, we first find the factors of each number: Factors of 28 are 1, 2, 4, 7, 14, and 28. Factors of 14 are 1, 2, 7, and 14. Factors of 21 are 1, 3, 7, and 21. The common factors among all three numbers are 1 and 7. Therefore, the HCF of 28, 14, and 21 is 7.
The HCF of 14 and 24 is 2.
The least common multiple of 14 and 21 is 42.14, 28, 42, 56 ...21, 42, 63, 84, ...
The GCF is 24.
The GCF is 7.
The GCF is 3.
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.
