Given numbers are 478,918,835,618,748
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 478,918,835,618,748 is 415132718220.
Find LCM of 478,918,835,618,748 with Prime Factorization
| 2 | 478, 918, 835, 618, 748 |
| 3 | 239, 459, 835, 309, 374 |
| 17 | 239, 153, 835, 103, 374 |
| 239, 9, 835, 103, 22 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 17 x 239 x 9 x 835 x 103 x 22 = 415132718220
Therefore, the lowest common multiple of 478,918,835,618,748 is 415132718220.
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.
478 x 918 x 835 x 618 x 748 = 169374149033760
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.
478 : 1, 2, 239, 478
918 : 1, 2, 3, 6, 9, 17, 18, 27, 34, 51, 54, 102, 153, 306, 459, 918
835 : 1, 5, 167, 835
618 : 1, 2, 3, 6, 103, 206, 309, 618
748 : 1, 2, 4, 11, 17, 22, 34, 44, 68, 187, 374, 748
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 478,918,835,618,748, is 1.
Now, the common factors can be found like this.
478:2x 239
918:2x 3x 3x 3x 17
835:5x 167
618:2x 3x 103
748:2x 2x 11x 17
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 2x 3x 17 = 408
Therefore, the value for common factors is 408.
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 = 169374149033760/(1x408)
LCM = 169374149033760/408
LCM = 415132718220
Thus, we can understand that the LCM of 478,918,835,618,748 is 415132718220.
