Given numbers are 873,454,669,645,915
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 873,454,669,645,915 is 1159159648590.
Find LCM of 873,454,669,645,915 with Prime Factorization
| 3 | 873, 454, 669, 645, 915 |
| 5 | 291, 454, 223, 215, 305 |
| 291, 454, 223, 43, 61 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 291 x 454 x 223 x 43 x 61 = 1159159648590
Therefore, the lowest common multiple of 873,454,669,645,915 is 1159159648590.
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.
873 x 454 x 669 x 645 x 915 = 156486552559650
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.
873 : 1, 3, 9, 97, 291, 873
454 : 1, 2, 227, 454
669 : 1, 3, 223, 669
645 : 1, 3, 5, 15, 43, 129, 215, 645
915 : 1, 3, 5, 15, 61, 183, 305, 915
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 873,454,669,645,915, is 1.
Now, the common factors can be found like this.
873:3x 3x 97
454:2x 227
669:3x 223
645:3x 5x 43
915:3x 5x 61
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 5 = 135
Therefore, the value for common factors is 135.
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 = 156486552559650/(1x135)
LCM = 156486552559650/135
LCM = 1159159648590
Thus, we can understand that the LCM of 873,454,669,645,915 is 1159159648590.
