How can we find HCF and LCM?

The highest common factor is found by multiplying all the factors which appear in both lists: So the HCF of 60 and 72 is 2 × 2 × 3 which is 12. The lowest common multiple is found by multiplying all the factors which appear in either list: So the LCM of 60 and 72 is 2 × 2 × 2 × 3 × 3 × 5 which is 360.

What is the full form of HCF and LCM?

HCF-HIGHEST COMMON FACTOR and LCM-LEAST COMMON MULTIPLE.

What is the HCF and LCM of 8 9 and 25?

Hence, the L.C.M of these three numbers is 1800. Hence, L.C.M of 8, 9 and 25 is 1800 and H.C.F of 8, 9 and 25 is 1.

How do you find the HCF of 8 and 9?

We found the factors and prime factorization of 8 and 9. The biggest common factor number is the GCF number. So the greatest common factor 8 and 9 is 1.

What is the HCF of 27?

The HCF of 27 and 36 is 9. To calculate the Highest common factor (HCF) of 27 and 36, we need to factor each number (factors of 27 = 1, 3, 9, 27; factors of 36 = 1, 2, 3, 4, 6, 9, 12, 18, 36) and choose the highest factor that exactly divides both 27 and 36, i.e., 9.

What is LCM expansion?

LCM (Least Common Multiple): A least number which is divisible by all the each of the given numbers is called a least common multiple. Example: Consider the numbers 4, 12, 15.

What is the HCF of 8/9 10/27 and 16/81?

L.C.M of 8/9, 10/27, 16/81 is L.C.M of 8,10 and 16 (the numerators) = 80/H.C.F of 9, 27, 81 (the denominators ) = 9 . So the L.C.M is 80/9. (ans) H.C.F of 8/9, 10/27 and 16/81 is H.C.F of 8,10, 16 (numerators) = 2/ L.C.M of 9,27, 81 (the denominators) = 81. So, the H.C.F is 2/81. (ans)

What is the LCM of 8/9 10/27 and 16/81?

L.C.M of 8/9, 10/27, 16/81 is L.C.M of 8,10 and 16 (the numerators) = 80/H.C.F of 9, 27, 81 (the denominators ) = 9 . So the L.C.M is 80/9. (ans) H.C.F of 8/9, 10/27 and 16/81 is H.C.F of 8,10, 16 (numerators) = 2/ L.C.M of 9,27, 81 (the denominators) = 81.
