Given numbers are 802,720,442,835,523
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 802,720,442,835,523 is 5572977667920.
Find LCM of 802,720,442,835,523 with Prime Factorization
| 2 | 802, 720, 442, 835, 523 |
| 5 | 401, 360, 221, 835, 523 |
| 401, 72, 221, 167, 523 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 401 x 72 x 221 x 167 x 523 = 5572977667920
Therefore, the lowest common multiple of 802,720,442,835,523 is 5572977667920.
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.
802 x 720 x 442 x 835 x 523 = 111459553358400
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.
802 : 1, 2, 401, 802
720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720
442 : 1, 2, 13, 17, 26, 34, 221, 442
835 : 1, 5, 167, 835
523 : 1, 523
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 802,720,442,835,523, is 1.
Now, the common factors can be found like this.
802:2x 401
720:2x 2x 2x 2x 3x 3x 5
442:2x 13x 17
835:5x 167
523:523
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 5 = 20
Therefore, the value for common factors is 20.
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 = 111459553358400/(1x20)
LCM = 111459553358400/20
LCM = 5572977667920
Thus, we can understand that the LCM of 802,720,442,835,523 is 5572977667920.
