There is really so such thing as a "greatest 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 greatest multiple.
The first few common multiples of 45 and 63 are: 315, 630, 945, 1260, and 1575.
Check your question again. It either must be greatest common factor or lowest common multiple. Because the greatest common multiple would be infinite!
9
The greatest common factor of 45 and 63 is 9.
The Greatest Common Factor of 45, 85, 63 and 18 is 1.
Greatest Common Factor= 1
The Greatest Common Factor (GCF) is: 9
The LCM of 14 and 63 is 126. The least common multiple of two numbers is the product of the two numbers divided by their greatest common factor. The greatest common factor of 14 and 63 is 7, so the least common multiple is 14 x 63 ÷ 7 = 126.
The GCF is 9.
The GCF is 9.
The greatest common multiple is an infinite amount and not very practical for problem solving.
The GCF is 3.
Greatest common factor (GCF) =7 Least common multiple (LCM) =693
The GCF is 9.
