Given numbers are 715,767,935,990
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 715,767,935,990 is 12908610.
Find LCM of 715,767,935,990 with Prime Factorization
| 5 | 715, 767, 935, 990 |
| 11 | 143, 767, 187, 198 |
| 13 | 13, 767, 17, 18 |
| 1, 59, 17, 18 |
Multiply the prime numbers at the bottom and the left side.
5 x 11 x 13 x 1 x 59 x 17 x 18 = 12908610
Therefore, the lowest common multiple of 715,767,935,990 is 12908610.
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.
715 x 767 x 935 x 990 = 507631088250
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.
715 : 1, 5, 11, 13, 55, 65, 143, 715
767 : 1, 13, 59, 767
935 : 1, 5, 11, 17, 55, 85, 187, 935
990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 715,767,935,990, is 1.
Now, the common factors can be found like this.
715:5x 11x 13
767:13x 59
935:5x 11x 17
990:2x 3x 3x 5x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5x 5x 11x 11x 13 = 39325
Therefore, the value for common factors is 39325.
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 = 507631088250/(1x39325)
LCM = 507631088250/39325
LCM = 12908610
Thus, we can understand that the LCM of 715,767,935,990 is 12908610.
