Find LCM of 972,891,886,517 with Prime Factorization
| 2 | 972, 891, 886, 517 |
| 3 | 486, 891, 443, 517 |
| 3 | 162, 297, 443, 517 |
| 3 | 54, 99, 443, 517 |
| 3 | 18, 33, 443, 517 |
| 11 | 6, 11, 443, 517 |
| 6, 1, 443, 47 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 3 x 3 x 11 x 6 x 1 x 443 x 47 = 222618132
Therefore, the lowest common multiple of 972,891,886,517 is 222618132.
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.
972 x 891 x 886 x 517 = 396705511224
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.
972 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 81, 108, 162, 243, 324, 486, 972
891 : 1, 3, 9, 11, 27, 33, 81, 99, 297, 891
886 : 1, 2, 443, 886
517 : 1, 11, 47, 517
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 972,891,886,517, is 1.
Now, the common factors can be found like this.
972:2x 2x 3x 3x 3x 3x 3
891:3x 3x 3x 3x 11
886:2x 443
517:11x 47
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 3x 3x 11 = 1782
Therefore, the value for common factors is 1782.
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 = 396705511224/(1x1782)
LCM = 396705511224/1782
LCM = 222618132
Thus, we can understand that the LCM of 972,891,886,517 is 222618132.
