Find LCM of 520,819,287,771,394 with Prime Factorization
| 2 | 520, 819, 287, 771, 394 |
| 3 | 260, 819, 287, 771, 197 |
| 7 | 260, 273, 287, 257, 197 |
| 13 | 260, 39, 41, 257, 197 |
| 20, 3, 41, 257, 197 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 13 x 20 x 3 x 41 x 257 x 197 = 68002847640
Therefore, the lowest common multiple of 520,819,287,771,394 is 68002847640.
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.
520 x 819 x 287 x 771 x 394 = 37129554811440
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.
520 : 1, 2, 4, 5, 8, 10, 13, 20, 26, 40, 52, 65, 104, 130, 260, 520
819 : 1, 3, 7, 9, 13, 21, 39, 63, 91, 117, 273, 819
287 : 1, 7, 41, 287
771 : 1, 3, 257, 771
394 : 1, 2, 197, 394
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 520,819,287,771,394, is 1.
Now, the common factors can be found like this.
520:2x 2x 2x 5x 13
819:3x 3x 7x 13
287:7x 41
771:3x 257
394:2x 197
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 7x 13 = 546
Therefore, the value for common factors is 546.
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 = 37129554811440/(1x546)
LCM = 37129554811440/546
LCM = 68002847640
Thus, we can understand that the LCM of 520,819,287,771,394 is 68002847640.
