Find LCM of 748,715,780,609 with Prime Factorization
| 2 | 748, 715, 780, 609 |
| 2 | 374, 715, 390, 609 |
| 3 | 187, 715, 195, 609 |
| 5 | 187, 715, 65, 203 |
| 11 | 187, 143, 13, 203 |
| 13 | 17, 13, 13, 203 |
| 17, 1, 1, 203 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 11 x 13 x 17 x 1 x 1 x 203 = 29609580
Therefore, the lowest common multiple of 748,715,780,609 is 29609580.
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.
748 x 715 x 780 x 609 = 254050196400
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.
748 : 1, 2, 4, 11, 17, 22, 34, 44, 68, 187, 374, 748
715 : 1, 5, 11, 13, 55, 65, 143, 715
780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780
609 : 1, 3, 7, 21, 29, 87, 203, 609
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 748,715,780,609, is 1.
Now, the common factors can be found like this.
748:2x 2x 11x 17
715:5x 11x 13
780:2x 2x 3x 5x 13
609:3x 7x 29
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 3x 5x 11x 13 = 8580
Therefore, the value for common factors is 8580.
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 = 254050196400/(1x8580)
LCM = 254050196400/8580
LCM = 29609580
Thus, we can understand that the LCM of 748,715,780,609 is 29609580.
