Given numbers are 835,215,824,780
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 835,215,824,780 is 1153843080.
Find LCM of 835,215,824,780 with Prime Factorization
| 2 | 835, 215, 824, 780 |
| 2 | 835, 215, 412, 390 |
| 5 | 835, 215, 206, 195 |
| 167, 43, 206, 39 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 167 x 43 x 206 x 39 = 1153843080
Therefore, the lowest common multiple of 835,215,824,780 is 1153843080.
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.
835 x 215 x 824 x 780 = 115384308000
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.
835 : 1, 5, 167, 835
215 : 1, 5, 43, 215
824 : 1, 2, 4, 8, 103, 206, 412, 824
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
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 835,215,824,780, is 1.
Now, the common factors can be found like this.
835:5x 167
215:5x 43
824:2x 2x 2x 103
780:2x 2x 3x 5x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 5x 5 = 100
Therefore, the value for common factors is 100.
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 = 115384308000/(1x100)
LCM = 115384308000/100
LCM = 1153843080
Thus, we can understand that the LCM of 835,215,824,780 is 1153843080.
