Find LCM of 824,385,555,970,840 with Prime Factorization
| 2 | 824, 385, 555, 970, 840 |
| 2 | 412, 385, 555, 485, 420 |
| 2 | 206, 385, 555, 485, 210 |
| 3 | 103, 385, 555, 485, 105 |
| 5 | 103, 385, 185, 485, 35 |
| 7 | 103, 77, 37, 97, 7 |
| 103, 11, 37, 97, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 5 x 7 x 103 x 11 x 37 x 97 x 1 = 3415723080
Therefore, the lowest common multiple of 824,385,555,970,840 is 3415723080.
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.
824 x 385 x 555 x 970 x 840 = 143460369360000
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.
824 : 1, 2, 4, 8, 103, 206, 412, 824
385 : 1, 5, 7, 11, 35, 55, 77, 385
555 : 1, 3, 5, 15, 37, 111, 185, 555
970 : 1, 2, 5, 10, 97, 194, 485, 970
840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 824,385,555,970,840, is 1.
Now, the common factors can be found like this.
824:2x 2x 2x 103
385:5x 7x 11
555:3x 5x 37
970:2x 5x 97
840:2x 2x 2x 3x 5x 7
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 3x 5x 5x 5x 7 = 42000
Therefore, the value for common factors is 42000.
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 = 143460369360000/(1x42000)
LCM = 143460369360000/42000
LCM = 3415723080
Thus, we can understand that the LCM of 824,385,555,970,840 is 3415723080.
