There is no greatest common multiple: for whatever value you say is the greatest I can always add their lowest common multiple (for 40 and 56 it is 280) and get an even greater common multiple.
There is a greatest common FACTOR or a LOWEST common multiple:
gcf(40, 56) = 8
lcm(40, 56) = 280
Using the factorisation method:
40 = 2³ x 5
56 = 2³ x 7
hcf = 2³ = 8
lcm = 2³ x 5 x 7 = 280
There is no such thing as a "greatest common multiple" of two numbers (or of one number, or of any set of numbers)! Once you find a common multiple (for example, calculating the LEAST common multiple, or simply multiplying the two numbers together), you can always find a larger common multiple - for example, just multiply the common multiple you found by 2. Since you can do this again, and again, and again... and always get a common multiple, there is no largest such number.In math, it is often convenient to find:
* The least common multiple, or
* The greatest common factor
The greatest common multiple of any set of integers is infinite.
There is no greatest common multiple: for whatever value you say is the greatest I can always add their lowest common multiple and get an even greater common multiple.There is a greatest common FACTOR or a LOWEST common multiple:gcf(40, 56, 96) = 8lcm(40, 56, 96) = 3360Using the factorisation method:40 = 2^3 x 556 = 2^3 x 796 = 2^5 x 3hcf = 2^3 = 8lcm = 2^5 x 3 x 5 x 7 = 3360
56 is a multiple of 7, and 56 is also a multiple of itself, so 56 isthe least common multiple of both numbers.There is no greatest common multiple. Whatever multiple you name,no matter how large it is, I can always add 56 to it and come up witha larger one.
The greatest common multiple of any set of numbers is infinite.
The greatest common multiple of any set of integers is infinite.
The greatest common factor of 24 and 56 is 8.The least common multiple of 24 and 56 is 168.
Greatest Common Factor of 56 72 and 40 is 8.
56 and 40's highest common factor is eight.
280
The GCF of 24, 40, and 56 is 8The GCF is 8.
The greatest common multiple of any set of integers is infinite.
The least common multiple is the product of the two numbers divided by their greatest common factor. Their greatest common factor is 8, so the least common multiple is 56 x 64 ÷ 8 = 448.
