Given numbers are 780,627,699,517
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 780,627,699,517 is 1785232020.
Find LCM of 780,627,699,517 with Prime Factorization
| 3 | 780, 627, 699, 517 |
| 11 | 260, 209, 233, 517 |
| 260, 19, 233, 47 |
Multiply the prime numbers at the bottom and the left side.
3 x 11 x 260 x 19 x 233 x 47 = 1785232020
Therefore, the lowest common multiple of 780,627,699,517 is 1785232020.
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.
780 x 627 x 699 x 517 = 176737969980
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.
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
627 : 1, 3, 11, 19, 33, 57, 209, 627
699 : 1, 3, 233, 699
517 : 1, 11, 47, 517
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 780,627,699,517, is 1.
Now, the common factors can be found like this.
780:2x 2x 3x 5x 13
627:3x 11x 19
699:3x 233
517:11x 47
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 11 = 99
Therefore, the value for common factors is 99.
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 = 176737969980/(1x99)
LCM = 176737969980/99
LCM = 1785232020
Thus, we can understand that the LCM of 780,627,699,517 is 1785232020.
