8. What is the LCM of 4 and 5? Can you find the highest common multiple of 4 and 5? Give reasons.
Answers
Answer:
The LCM of 4 and 5 is 20. To find the LCM of 4 and 5, we need to find the multiples of 4 and 5 (multiples of 4 = 4, 8, 12, 16 . . . . 20; multiples of 5 = 5, 10, 15, 20) and choose the smallest multiple that is exactly divisible by 4 and 5, i.e., 20.
To find the HCF of 4 and 5, we will find the prime factorization of the given numbers, i.e. 4 = 2 × 2; 5 = 5. ⇒ There is no common prime factor for 4 and 5. Hence, HCF (4, 5) = 1.

Answer:
what is the LCM of 4 and 5?
ans. 20
Step-by-step explanation:
Can you find the highest common multiple of 4 and 5? Give reasons.
ans.The highest common factor of two numbers is the largest whole number which is a factor of both. This can sometimes also be called the Greatest Common Factor (GCF). Factors are whole numbers we can multiply together to get another number, for example, 4 and 5 are factors of 20 because 4 x 5 = 20.
