Find LCM of 441,428,920,360,279 with Prime Factorization
| 2 | 441, 428, 920, 360, 279 |
| 2 | 441, 214, 460, 180, 279 |
| 2 | 441, 107, 230, 90, 279 |
| 3 | 441, 107, 115, 45, 279 |
| 3 | 147, 107, 115, 15, 93 |
| 5 | 49, 107, 115, 5, 31 |
| 49, 107, 23, 1, 31 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 3 x 5 x 49 x 107 x 23 x 1 x 31 = 1345773240
Therefore, the lowest common multiple of 441,428,920,360,279 is 1345773240.
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.
441 x 428 x 920 x 360 x 279 = 17441221190400
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.
441 : 1, 3, 7, 9, 21, 49, 63, 147, 441
428 : 1, 2, 4, 107, 214, 428
920 : 1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920
360 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 18, 20, 24, 30, 36, 40, 45, 60, 72, 90, 120, 180, 360
279 : 1, 3, 9, 31, 93, 279
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 441,428,920,360,279, is 1.
Now, the common factors can be found like this.
441:3x 3x 7x 7
428:2x 2x 107
920:2x 2x 2x 5x 23
360:2x 2x 2x 3x 3x 5
279:3x 3x 31
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 2x 2x 2x 3x 3x 3x 3x 5 = 12960
Therefore, the value for common factors is 12960.
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 = 17441221190400/(1x12960)
LCM = 17441221190400/12960
LCM = 1345773240
Thus, we can understand that the LCM of 441,428,920,360,279 is 1345773240.
