Find LCM of 437,828,779,18 with Prime Factorization
| 2 | 437, 828, 779, 18 |
| 3 | 437, 414, 779, 9 |
| 3 | 437, 138, 779, 3 |
| 19 | 437, 46, 779, 1 |
| 23 | 23, 46, 41, 1 |
| 1, 2, 41, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 19 x 23 x 1 x 2 x 41 x 1 = 645012
Therefore, the lowest common multiple of 437,828,779,18 is 645012.
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.
437 x 828 x 779 x 18 = 5073664392
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.
437 : 1, 19, 23, 437
828 : 1, 2, 3, 4, 6, 9, 12, 18, 23, 36, 46, 69, 92, 138, 207, 276, 414, 828
779 : 1, 19, 41, 779
18 : 1, 2, 3, 6, 9, 18
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 437,828,779,18, is 1.
Now, the common factors can be found like this.
437:19x 23
828:2x 2x 3x 3x 23
779:19x 41
18:2x 3x 3
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 19x 23 = 7866
Therefore, the value for common factors is 7866.
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 = 5073664392/(1x7866)
LCM = 5073664392/7866
LCM = 645012
Thus, we can understand that the LCM of 437,828,779,18 is 645012.
