Hcf and lcm of 12 21 15

WebUsing the HCF and LCM formula, we can find the unknown value. HCF (a, b) × LCM (a, b) = a × b After substituting the values we get, 8 × 96 = 24 × b So the value of 'b' = 768/24 = 32. Therefore, the other number is 32. Note: Similarly, we can find the LCM of two numbers if we know the two numbers and the HCF using the same formula. WebMultiples of 15 are: 15, 30, 45, 60, 75, etc. Factors of 15 are: 1, 3, 5, and 15 Now, how do these apply to GCF and LCM. Let's find the GCF of 15 and 9 Prime factors of 15 = 3 * 5 Prime factors of 9 = 3 * 3 The 2 numbers share one common factor. The GCF = 3.
