Given numbers are 820,779,802,208,863
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 820,779,802,208,863 is 280366400080.
Find LCM of 820,779,802,208,863 with Prime Factorization
2 | 820, 779, 802, 208, 863 |
2 | 410, 779, 401, 104, 863 |
41 | 205, 779, 401, 52, 863 |
5, 19, 401, 52, 863 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 41 x 5 x 19 x 401 x 52 x 863 = 280366400080
Therefore, the lowest common multiple of 820,779,802,208,863 is 280366400080.
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.
820 x 779 x 802 x 208 x 863 = 91960179226240
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.
820 : 1, 2, 4, 5, 10, 20, 41, 82, 164, 205, 410, 820
779 : 1, 19, 41, 779
802 : 1, 2, 401, 802
208 : 1, 2, 4, 8, 13, 16, 26, 52, 104, 208
863 : 1, 863
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 820,779,802,208,863, is 1.
Now, the common factors can be found like this.
820:2x 2x 5x 41
779:19x 41
802:2x 401
208:2x 2x 2x 2x 13
863:863
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 2x 41 = 328
Therefore, the value for common factors is 328.
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 = 91960179226240/(1x328)
LCM = 91960179226240/328
LCM = 280366400080
Thus, we can understand that the LCM of 820,779,802,208,863 is 280366400080.
