Find LCM of 363,858,280,520 with Prime Factorization
| 2 | 363, 858, 280, 520 |
| 2 | 363, 429, 140, 260 |
| 2 | 363, 429, 70, 130 |
| 3 | 363, 429, 35, 65 |
| 5 | 121, 143, 35, 65 |
| 11 | 121, 143, 7, 13 |
| 13 | 11, 13, 7, 13 |
| 11, 1, 7, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 5 x 11 x 13 x 11 x 1 x 7 x 1 = 1321320
Therefore, the lowest common multiple of 363,858,280,520 is 1321320.
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.
363 x 858 x 280 x 520 = 45347702400
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.
363 : 1, 3, 11, 33, 121, 363
858 : 1, 2, 3, 6, 11, 13, 22, 26, 33, 39, 66, 78, 143, 286, 429, 858
280 : 1, 2, 4, 5, 7, 8, 10, 14, 20, 28, 35, 40, 56, 70, 140, 280
520 : 1, 2, 4, 5, 8, 10, 13, 20, 26, 40, 52, 65, 104, 130, 260, 520
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 363,858,280,520, is 1.
Now, the common factors can be found like this.
363:3x 11x 11
858:2x 3x 11x 13
280:2x 2x 2x 5x 7
520:2x 2x 2x 5x 13
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 11x 13 = 34320
Therefore, the value for common factors is 34320.
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 = 45347702400/(1x34320)
LCM = 45347702400/34320
LCM = 1321320
Thus, we can understand that the LCM of 363,858,280,520 is 1321320.
