Given numbers are 1,715,968,715
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 1,715,968,715 is 62920.
Find LCM of 1,715,968,715 with Prime Factorization
| 5 | 1, 715, 968, 715 |
| 11 | 1, 143, 968, 143 |
| 13 | 1, 13, 88, 13 |
| 1, 1, 88, 1 |
Multiply the prime numbers at the bottom and the left side.
5 x 11 x 13 x 1 x 1 x 88 x 1 = 62920
Therefore, the lowest common multiple of 1,715,968,715 is 62920.
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.
1 x 715 x 968 x 715 = 494865800
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.
1 : 1
715 : 1, 5, 11, 13, 55, 65, 143, 715
968 : 1, 2, 4, 8, 11, 22, 44, 88, 121, 242, 484, 968
715 : 1, 5, 11, 13, 55, 65, 143, 715
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 1,715,968,715, is 1.
Now, the common factors can be found like this.
1:
715:5x 11x 13
968:2x 2x 2x 11x 11
715:5x 11x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5x 11x 11x 13 = 7865
Therefore, the value for common factors is 7865.
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 = 494865800/(1x7865)
LCM = 494865800/7865
LCM = 62920
Thus, we can understand that the LCM of 1,715,968,715 is 62920.
