Given numbers are 1812,1944
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 1812,1944 is 293544.
Find LCM of 1812,1944 with Prime Factorization
| 2 | 1812, 1944 |
| 2 | 906, 972 |
| 3 | 453, 486 |
| 151, 162 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 151 x 162 = 293544
Therefore, the lowest common multiple of 1812,1944 is 293544.
LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
Firstly, we have to find the product of all the numbers.
1812 x 1944 = 3522528
Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.
1812 : 1, 2, 3, 4, 6, 12, 151, 302, 453, 604, 906, 1812
1944 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 81, 108, 162, 216, 243, 324, 486, 648, 972, 1944
12 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 1812,1944, is 12.
Now, the common factors can be found like this.
1812:2x 2x 3x 151
1944:2x 2x 2x 3x 3x 3x 3x 3
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
= 1
Therefore, the value for common factors is 1.
Now that we have all the elements of the formula, we can plug them in to calculate the LCM.
LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
LCM = 3522528/(12x1)
LCM = 3522528/12
LCM = 293544
Thus, we can understand that the LCM of 1812,1944 is 293544.
