Given numbers are 418,714,993,428
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 418,714,993,428 is 10570274484.
Find LCM of 418,714,993,428 with Prime Factorization
| 2 | 418, 714, 993, 428 |
| 3 | 209, 357, 993, 214 |
| 209, 119, 331, 214 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 209 x 119 x 331 x 214 = 10570274484
Therefore, the lowest common multiple of 418,714,993,428 is 10570274484.
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.
418 x 714 x 993 x 428 = 126843293808
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.
418 : 1, 2, 11, 19, 22, 38, 209, 418
714 : 1, 2, 3, 6, 7, 14, 17, 21, 34, 42, 51, 102, 119, 238, 357, 714
993 : 1, 3, 331, 993
428 : 1, 2, 4, 107, 214, 428
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 418,714,993,428, is 1.
Now, the common factors can be found like this.
418:2x 11x 19
714:2x 3x 7x 17
993:3x 331
428:2x 2x 107
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 3 = 12
Therefore, the value for common factors is 12.
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 = 126843293808/(1x12)
LCM = 126843293808/12
LCM = 10570274484
Thus, we can understand that the LCM of 418,714,993,428 is 10570274484.
