Given numbers are 228,442,663,770,809
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 228,442,663,770,809 is 15694098420.
Find LCM of 228,442,663,770,809 with Prime Factorization
| 2 | 228, 442, 663, 770, 809 |
| 3 | 114, 221, 663, 385, 809 |
| 13 | 38, 221, 221, 385, 809 |
| 17 | 38, 17, 17, 385, 809 |
| 38, 1, 1, 385, 809 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 13 x 17 x 38 x 1 x 1 x 385 x 809 = 15694098420
Therefore, the lowest common multiple of 228,442,663,770,809 is 15694098420.
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.
228 x 442 x 663 x 770 x 809 = 41620749009840
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.
228 : 1, 2, 3, 4, 6, 12, 19, 38, 57, 76, 114, 228
442 : 1, 2, 13, 17, 26, 34, 221, 442
663 : 1, 3, 13, 17, 39, 51, 221, 663
770 : 1, 2, 5, 7, 10, 11, 14, 22, 35, 55, 70, 77, 110, 154, 385, 770
809 : 1, 809
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 228,442,663,770,809, is 1.
Now, the common factors can be found like this.
228:2x 2x 3x 19
442:2x 13x 17
663:3x 13x 17
770:2x 5x 7x 11
809:809
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 13x 17 = 2652
Therefore, the value for common factors is 2652.
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 = 41620749009840/(1x2652)
LCM = 41620749009840/2652
LCM = 15694098420
Thus, we can understand that the LCM of 228,442,663,770,809 is 15694098420.
