Given numbers are 808,710,110,638
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 808,710,110,638 is 91501960.
Find LCM of 808,710,110,638 with Prime Factorization
| 2 | 808, 710, 110, 638 |
| 5 | 404, 355, 55, 319 |
| 11 | 404, 71, 11, 319 |
| 404, 71, 1, 29 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 11 x 404 x 71 x 1 x 29 = 91501960
Therefore, the lowest common multiple of 808,710,110,638 is 91501960.
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.
808 x 710 x 110 x 638 = 40260862400
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.
808 : 1, 2, 4, 8, 101, 202, 404, 808
710 : 1, 2, 5, 10, 71, 142, 355, 710
110 : 1, 2, 5, 10, 11, 22, 55, 110
638 : 1, 2, 11, 22, 29, 58, 319, 638
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 808,710,110,638, is 2.
Now, the common factors can be found like this.
808:2x 2x 2x 101
710:2x 5x 71
110:2x 5x 11
638:2x 11x 29
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 5x 11 = 220
Therefore, the value for common factors is 220.
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 = 40260862400/(2x220)
LCM = 40260862400/440
LCM = 91501960
Thus, we can understand that the LCM of 808,710,110,638 is 91501960.
