Given numbers are 444,307,449,378,921
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 444,307,449,378,921 is 3855744396.
Find LCM of 444,307,449,378,921 with Prime Factorization
| 2 | 444, 307, 449, 378, 921 |
| 3 | 222, 307, 449, 189, 921 |
| 307 | 74, 307, 449, 63, 307 |
| 74, 1, 449, 63, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 307 x 74 x 1 x 449 x 63 x 1 = 3855744396
Therefore, the lowest common multiple of 444,307,449,378,921 is 3855744396.
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.
444 x 307 x 449 x 378 x 921 = 21306843532296
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.
444 : 1, 2, 3, 4, 6, 12, 37, 74, 111, 148, 222, 444
307 : 1, 307
449 : 1, 449
378 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 27, 42, 54, 63, 126, 189, 378
921 : 1, 3, 307, 921
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 444,307,449,378,921, is 1.
Now, the common factors can be found like this.
444:2x 2x 3x 37
307:307
449:449
378:2x 3x 3x 3x 7
921:3x 307
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 307 = 5526
Therefore, the value for common factors is 5526.
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 = 21306843532296/(1x5526)
LCM = 21306843532296/5526
LCM = 3855744396
Thus, we can understand that the LCM of 444,307,449,378,921 is 3855744396.
