Find LCM of 833,715,308,455 with Prime Factorization
| 5 | 833, 715, 308, 455 |
| 7 | 833, 143, 308, 91 |
| 11 | 119, 143, 44, 13 |
| 13 | 119, 13, 4, 13 |
| 119, 1, 4, 1 |
Multiply the prime numbers at the bottom and the left side.
5 x 7 x 11 x 13 x 119 x 1 x 4 x 1 = 2382380
Therefore, the lowest common multiple of 833,715,308,455 is 2382380.
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.
833 x 715 x 308 x 455 = 83466683300
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.
833 : 1, 7, 17, 49, 119, 833
715 : 1, 5, 11, 13, 55, 65, 143, 715
308 : 1, 2, 4, 7, 11, 14, 22, 28, 44, 77, 154, 308
455 : 1, 5, 7, 13, 35, 65, 91, 455
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 833,715,308,455, is 1.
Now, the common factors can be found like this.
833:7x 7x 17
715:5x 11x 13
308:2x 2x 7x 11
455:5x 7x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5x 7x 7x 11x 13 = 35035
Therefore, the value for common factors is 35035.
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 = 83466683300/(1x35035)
LCM = 83466683300/35035
LCM = 2382380
Thus, we can understand that the LCM of 833,715,308,455 is 2382380.
