Given numbers are 418,994,618,917
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 418,994,618,917 is 8409350334.
Find LCM of 418,994,618,917 with Prime Factorization
| 2 | 418, 994, 618, 917 |
| 7 | 209, 497, 309, 917 |
| 209, 71, 309, 131 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 209 x 71 x 309 x 131 = 8409350334
Therefore, the lowest common multiple of 418,994,618,917 is 8409350334.
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 994 x 618 x 917 = 235461809352
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
994 : 1, 2, 7, 14, 71, 142, 497, 994
618 : 1, 2, 3, 6, 103, 206, 309, 618
917 : 1, 7, 131, 917
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 418,994,618,917, is 1.
Now, the common factors can be found like this.
418:2x 11x 19
994:2x 7x 71
618:2x 3x 103
917:7x 131
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 7 = 28
Therefore, the value for common factors is 28.
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 = 235461809352/(1x28)
LCM = 235461809352/28
LCM = 8409350334
Thus, we can understand that the LCM of 418,994,618,917 is 8409350334.
