To find the two numbers, we need to consider that their highest common factor is 8 and their lowest common multiple is a multiple of 5. The numbers that satisfy these conditions are multiples of 8 and 5. Therefore, the two numbers are 40 and 80, as they have a highest common factor of 8 and a lowest common multiple of 40.

JudyWell, isn't that just a happy little math problem we have here! Let's see, if the highest common factor is 8, then the two numbers must both be multiples of 8. And if the lowest common multiple is a multiple of 5, then the two numbers must also be multiples of 5. So, the two numbers Niamh is thinking of are 40 and 80. Happy calculating!

What is the highest common multiple of 3 and 5?
The highest common multiple of two numbers is their least common multiple (LCM). The LCM of 3 and 5 is found by multiplying the two numbers and dividing by their greatest common divisor (GCD). In this case, the LCM of 3 and 5 is 15, as 3 * 5 / 1 = 15.
Are 36 and 48 coprime?
No. The two numbers have multiple common factors, the highest of which is 12.
What is the highest common multiple of 6 and 15?
There is really no such thing as a "highest common multiple". Once you find the least common multiple of a set of numbers, you can keep adding the LCM to itself over and over again. Each new number you get will be a common multiple of your set of numbers, but each new number will always be larger than the previous. This means that you can keep adding while the number approaches infinity and you will still never find a highest multiple.
What is the least common multiple of 2149?
There is no LCM for less than two numbers. LCM is the multiple of the highest power of prime factors in two or more numbers. Example: LCM of 9, 15, and 25 is 225, which is the multiple of the highest power of prime factors in 9, 15, and 25 (32 x 52).
What is the LCM of 51?
There is no LCM for less than two numbers. LCM is the multiple of the highest power of prime factors in two or more numbers. Example: LCM of 9, 15, and 25 is 225, which is the multiple of the highest power of prime factors in 9, 15, and 25 (32 x 52).
