The LCM of 707,391,630,645,266 is 20326412610.
Find LCM of 707,391,630,645,266 with Prime Factorization
| 2 | 707, 391, 630, 645, 266 |
| 3 | 707, 391, 315, 645, 133 |
| 5 | 707, 391, 105, 215, 133 |
| 7 | 707, 391, 21, 43, 133 |
| 101, 391, 3, 43, 19 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 7 x 101 x 391 x 3 x 43 x 19 = 20326412610
Therefore, the lowest common multiple of 707,391,630,645,266 is 20326412610.
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.
707 x 391 x 630 x 645 x 266 = 29879826536700
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.
707 : 1, 7, 101, 707
391 : 1, 17, 23, 391
630 : 1, 2, 3, 5, 6, 7, 9, 10, 14, 15, 18, 21, 30, 35, 42, 45, 63, 70, 90, 105, 126, 210, 315, 630
645 : 1, 3, 5, 15, 43, 129, 215, 645
266 : 1, 2, 7, 14, 19, 38, 133, 266
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 707,391,630,645,266, is 1.
Now, the common factors can be found like this.
707:7x 101
391:17x 23
630:2x 3x 3x 5x 7
645:3x 5x 43
266:2x 7x 19
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 5x 7x 7 = 1470
Therefore, the value for common factors is 1470.
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 = 29879826536700/(1x1470)
LCM = 29879826536700/1470
LCM = 20326412610
Thus, we can understand that the LCM of 707,391,630,645,266 is 20326412610.
