Find LCM of 371,828,836,770,915 with Prime Factorization
| 2 | 371, 828, 836, 770, 915 |
| 2 | 371, 414, 418, 385, 915 |
| 3 | 371, 207, 209, 385, 915 |
| 5 | 371, 69, 209, 385, 305 |
| 7 | 371, 69, 209, 77, 61 |
| 11 | 53, 69, 209, 11, 61 |
| 53, 69, 19, 1, 61 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 7 x 11 x 53 x 69 x 19 x 1 x 61 = 19581699060
Therefore, the lowest common multiple of 371,828,836,770,915 is 19581699060.
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.
371 x 828 x 836 x 770 x 915 = 180934899314400
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.
371 : 1, 7, 53, 371
828 : 1, 2, 3, 4, 6, 9, 12, 18, 23, 36, 46, 69, 92, 138, 207, 276, 414, 828
836 : 1, 2, 4, 11, 19, 22, 38, 44, 76, 209, 418, 836
770 : 1, 2, 5, 7, 10, 11, 14, 22, 35, 55, 70, 77, 110, 154, 385, 770
915 : 1, 3, 5, 15, 61, 183, 305, 915
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 371,828,836,770,915, is 1.
Now, the common factors can be found like this.
371:7x 53
828:2x 2x 3x 3x 23
836:2x 2x 11x 19
770:2x 5x 7x 11
915:3x 5x 61
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 3x 5x 7x 11 = 9240
Therefore, the value for common factors is 9240.
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 = 180934899314400/(1x9240)
LCM = 180934899314400/9240
LCM = 19581699060
Thus, we can understand that the LCM of 371,828,836,770,915 is 19581699060.
