Given numbers are 818,618,309,748
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 818,618,309,748 is 94532988.
Find LCM of 818,618,309,748 with Prime Factorization
| 2 | 818, 618, 309, 748 |
| 3 | 409, 309, 309, 374 |
| 103 | 409, 103, 103, 374 |
| 409, 1, 1, 374 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 103 x 409 x 1 x 1 x 374 = 94532988
Therefore, the lowest common multiple of 818,618,309,748 is 94532988.
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.
818 x 618 x 309 x 748 = 116842773168
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.
818 : 1, 2, 409, 818
618 : 1, 2, 3, 6, 103, 206, 309, 618
309 : 1, 3, 103, 309
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 818,618,309,748, is 1.
Now, the common factors can be found like this.
818:2x 409
618:2x 3x 103
309:3x 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 3x 103 = 1236
Therefore, the value for common factors is 1236.
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 = 116842773168/(1x1236)
LCM = 116842773168/1236
LCM = 94532988
Thus, we can understand that the LCM of 818,618,309,748 is 94532988.
