Given numbers are 779,287,724,518
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 779,287,724,518 is 146074964.
Find LCM of 779,287,724,518 with Prime Factorization
| 2 | 779, 287, 724, 518 |
| 7 | 779, 287, 362, 259 |
| 41 | 779, 41, 362, 37 |
| 19, 1, 362, 37 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 41 x 19 x 1 x 362 x 37 = 146074964
Therefore, the lowest common multiple of 779,287,724,518 is 146074964.
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.
779 x 287 x 724 x 518 = 83847029336
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.
779 : 1, 19, 41, 779
287 : 1, 7, 41, 287
724 : 1, 2, 4, 181, 362, 724
518 : 1, 2, 7, 14, 37, 74, 259, 518
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 779,287,724,518, is 1.
Now, the common factors can be found like this.
779:19x 41
287:7x 41
724:2x 2x 181
518:2x 7x 37
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 7x 41 = 574
Therefore, the value for common factors is 574.
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 = 83847029336/(1x574)
LCM = 83847029336/574
LCM = 146074964
Thus, we can understand that the LCM of 779,287,724,518 is 146074964.
