The LCM of 704,715,140,234,343 is 141261120.
Find LCM of 704,715,140,234,343 with Prime Factorization
| 2 | 704, 715, 140, 234, 343 |
| 2 | 352, 715, 70, 117, 343 |
| 5 | 176, 715, 35, 117, 343 |
| 7 | 176, 143, 7, 117, 343 |
| 11 | 176, 143, 1, 117, 49 |
| 13 | 16, 13, 1, 117, 49 |
| 16, 1, 1, 9, 49 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 7 x 11 x 13 x 16 x 1 x 1 x 9 x 49 = 141261120
Therefore, the lowest common multiple of 704,715,140,234,343 is 141261120.
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.
704 x 715 x 140 x 234 x 343 = 5656095244800
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.
704 : 1, 2, 4, 8, 11, 16, 22, 32, 44, 64, 88, 176, 352, 704
715 : 1, 5, 11, 13, 55, 65, 143, 715
140 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 70, 140
234 : 1, 2, 3, 6, 9, 13, 18, 26, 39, 78, 117, 234
343 : 1, 7, 49, 343
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 704,715,140,234,343, is 1.
Now, the common factors can be found like this.
704:2x 2x 2x 2x 2x 2x 11
715:5x 11x 13
140:2x 2x 5x 7
234:2x 3x 3x 13
343:7x 7x 7
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 5x 7x 11x 13 = 40040
Therefore, the value for common factors is 40040.
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 = 5656095244800/(1x40040)
LCM = 5656095244800/40040
LCM = 141261120
Thus, we can understand that the LCM of 704,715,140,234,343 is 141261120.
