Given numbers are 328,878,654,618
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 328,878,654,618 is 4849794552.
Find LCM of 328,878,654,618 with Prime Factorization
| 2 | 328, 878, 654, 618 |
| 3 | 164, 439, 327, 309 |
| 164, 439, 109, 103 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 164 x 439 x 109 x 103 = 4849794552
Therefore, the lowest common multiple of 328,878,654,618 is 4849794552.
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.
328 x 878 x 654 x 618 = 116395069248
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.
328 : 1, 2, 4, 8, 41, 82, 164, 328
878 : 1, 2, 439, 878
654 : 1, 2, 3, 6, 109, 218, 327, 654
618 : 1, 2, 3, 6, 103, 206, 309, 618
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 328,878,654,618, is 2.
Now, the common factors can be found like this.
328:2x 2x 2x 41
878:2x 439
654:2x 3x 109
618:2x 3x 103
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 = 116395069248/(2x12)
LCM = 116395069248/24
LCM = 4849794552
Thus, we can understand that the LCM of 328,878,654,618 is 4849794552.
