Find LCM of 715,858,572,168,394 with Prime Factorization
| 2 | 715, 858, 572, 168, 394 |
| 2 | 715, 429, 286, 84, 197 |
| 3 | 715, 429, 143, 42, 197 |
| 11 | 715, 143, 143, 14, 197 |
| 13 | 65, 13, 13, 14, 197 |
| 5, 1, 1, 14, 197 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 11 x 13 x 5 x 1 x 1 x 14 x 197 = 23663640
Therefore, the lowest common multiple of 715,858,572,168,394 is 23663640.
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.
715 x 858 x 572 x 168 x 394 = 23227093169280
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.
715 : 1, 5, 11, 13, 55, 65, 143, 715
858 : 1, 2, 3, 6, 11, 13, 22, 26, 33, 39, 66, 78, 143, 286, 429, 858
572 : 1, 2, 4, 11, 13, 22, 26, 44, 52, 143, 286, 572
168 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 21, 24, 28, 42, 56, 84, 168
394 : 1, 2, 197, 394
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 715,858,572,168,394, is 1.
Now, the common factors can be found like this.
715:5x 11x 13
858:2x 3x 11x 13
572:2x 2x 11x 13
168:2x 2x 2x 3x 7
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 2x 2x 2x 3x 11x 11x 13x 13 = 981552
Therefore, the value for common factors is 981552.
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 = 23227093169280/(1x981552)
LCM = 23227093169280/981552
LCM = 23663640
Thus, we can understand that the LCM of 715,858,572,168,394 is 23663640.
