Find LCM of 216,979,715,285,841 with Prime Factorization
| 3 | 216, 979, 715, 285, 841 |
| 5 | 72, 979, 715, 95, 841 |
| 11 | 72, 979, 143, 19, 841 |
| 72, 89, 13, 19, 841 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 11 x 72 x 89 x 13 x 19 x 841 = 219633911640
Therefore, the lowest common multiple of 216,979,715,285,841 is 219633911640.
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.
216 x 979 x 715 x 285 x 841 = 36239595420600
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.
216 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 108, 216
979 : 1, 11, 89, 979
715 : 1, 5, 11, 13, 55, 65, 143, 715
285 : 1, 3, 5, 15, 19, 57, 95, 285
841 : 1, 29, 841
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 216,979,715,285,841, is 1.
Now, the common factors can be found like this.
216:2x 2x 2x 3x 3x 3
979:11x 89
715:5x 11x 13
285:3x 5x 19
841:29x 29
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 5x 11 = 165
Therefore, the value for common factors is 165.
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 = 36239595420600/(1x165)
LCM = 36239595420600/165
LCM = 219633911640
Thus, we can understand that the LCM of 216,979,715,285,841 is 219633911640.
