Find LCM of 325,429,972,891 with Prime Factorization
| 3 | 325, 429, 972, 891 |
| 3 | 325, 143, 324, 297 |
| 3 | 325, 143, 108, 99 |
| 3 | 325, 143, 36, 33 |
| 11 | 325, 143, 12, 11 |
| 13 | 325, 13, 12, 1 |
| 25, 1, 12, 1 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 3 x 3 x 11 x 13 x 25 x 1 x 12 x 1 = 3474900
Therefore, the lowest common multiple of 325,429,972,891 is 3474900.
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.
325 x 429 x 972 x 891 = 120749300100
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.
325 : 1, 5, 13, 25, 65, 325
429 : 1, 3, 11, 13, 33, 39, 143, 429
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
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 325,429,972,891, is 1.
Now, the common factors can be found like this.
325:5x 5x 13
429:3x 11x 13
972:2x 2x 3x 3x 3x 3x 3
891:3x 3x 3x 3x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 3x 3x 3x 11x 13 = 34749
Therefore, the value for common factors is 34749.
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 = 120749300100/(1x34749)
LCM = 120749300100/34749
LCM = 3474900
Thus, we can understand that the LCM of 325,429,972,891 is 3474900.
