Given numbers are 645,818,744,415,326
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 645,818,744,415,326 is 885116425560.
Find LCM of 645,818,744,415,326 with Prime Factorization
| 2 | 645, 818, 744, 415, 326 |
| 3 | 645, 409, 372, 415, 163 |
| 5 | 215, 409, 124, 415, 163 |
| 43, 409, 124, 83, 163 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 43 x 409 x 124 x 83 x 163 = 885116425560
Therefore, the lowest common multiple of 645,818,744,415,326 is 885116425560.
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.
645 x 818 x 744 x 415 x 326 = 53106985533600
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.
645 : 1, 3, 5, 15, 43, 129, 215, 645
818 : 1, 2, 409, 818
744 : 1, 2, 3, 4, 6, 8, 12, 24, 31, 62, 93, 124, 186, 248, 372, 744
415 : 1, 5, 83, 415
326 : 1, 2, 163, 326
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 645,818,744,415,326, is 1.
Now, the common factors can be found like this.
645:3x 5x 43
818:2x 409
744:2x 2x 2x 3x 31
415:5x 83
326:2x 163
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 3x 5 = 60
Therefore, the value for common factors is 60.
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 = 53106985533600/(1x60)
LCM = 53106985533600/60
LCM = 885116425560
Thus, we can understand that the LCM of 645,818,744,415,326 is 885116425560.
