Given numbers are 983,390,715,539
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 983,390,715,539 is 206636430.
Find LCM of 983,390,715,539 with Prime Factorization
| 5 | 983, 390, 715, 539 |
| 11 | 983, 78, 143, 539 |
| 13 | 983, 78, 13, 49 |
| 983, 6, 1, 49 |
Multiply the prime numbers at the bottom and the left side.
5 x 11 x 13 x 983 x 6 x 1 x 49 = 206636430
Therefore, the lowest common multiple of 983,390,715,539 is 206636430.
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.
983 x 390 x 715 x 539 = 147745047450
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.
983 : 1, 983
390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390
715 : 1, 5, 11, 13, 55, 65, 143, 715
539 : 1, 7, 11, 49, 77, 539
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 983,390,715,539, is 1.
Now, the common factors can be found like this.
983:983
390:2x 3x 5x 13
715:5x 11x 13
539:7x 7x 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 11x 13 = 715
Therefore, the value for common factors is 715.
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 = 147745047450/(1x715)
LCM = 147745047450/715
LCM = 206636430
Thus, we can understand that the LCM of 983,390,715,539 is 206636430.
