The LCM of these is the lowest whole number which is evenly divisible by all the numbers. It is the smallest number which is a common (i.e. a shared) multiple of all the numbers.
The answer is 360. This is because, starting at 0 and then looking at every following positive integer (whole number), 360 is the first (i.e. the lowest) number which divides evenly by all the other numbers.
A factor of a number is a positive whole number which evenly divides into the number. So, for example, 1 will always be a factor of every number. If we write down (in descendingorder) all the factors of one of the numbers (often it is easiest to pick the smallest number, but not always) then we can look at each in turn and ask which of these is the first common (shared) factor.
The factors of 10 are 10,5,2 and 1. The first number here which is also a factor of both 24 and 45 is 1. Therefore the greatest common factor (indeed the only common factor) is 1.
The GCF of 32 and 45 is 1.
The LCM of 32 and 45 is 1440.
Using prime factorisation:
36 = 2² x 3²
45 = 3² x 5
→hcf = 3² = 9
→lcm = 2² x 3² x 5 = 180
2 x 2 x 3 x 3 = 36
3 x 3 x 5 = 45
3 x 3 = 9, the GCF
2 x 2 x 3 x 3 x 5 = 180, the LCM
Check it.
36 x 45 = 1620
180 x 9 = 1620
It checks.
The GCF is 9.
The LCM is 180.

The Greatest Common Factor (GCF) of (32,49) is 1The Least Common Multiple (LCM) of (32,49) is 1568
The LCM or least common multiple of 3 and 5 is 15.The GCF or greatest common factor of 3 and 5 is 1.
The least common multiple is 24. The greatest common factor is 4.
The least common factor is ' 1 '. The greatest common factor is ' 2 '. 1 and 2 are the only common factors. The least common multiple is ' 8 '.
The greatest common factor can't be a smaller number than the least common factor, but if you meant least common multiple, 7 and 28 have a GCF of 7 and an LCM of 28.
The greatest common factor is 2 and the least common multiple is also 2.
Greatest common factor (GCF) =7 Least common multiple (LCM) =693
The greatest common factor of 20 and 120 is 20, and the least common multiple of 20 and 120 is 120
The Greatest Common Factor (GCF) of (32,49) is 1The Least Common Multiple (LCM) of (32,49) is 1568
The greatest common factor(gcf) of 4 and 32 is 4. The least common multiple of 4 and 32 is 32.
The greatest common multiple is infinitely large, the least common multiple is 1365, the greatest common factor is 1.
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.
Itself
The least common multiple is the product of the two numbers divided by their greatest common factor. The greatest common factor of 44 and 60 is 4, so the least common multiple is 44 x 60 ÷ 4 = 660.
the least common multiple is what the numbers you are using divide into. e.g. 3 and 6 have 12 as the common factor. the greatest common factor is what divides into your numbers. 6 and 9 have 3 as the greatest common factor
