Given numbers are 749,581,143,806
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 749,581,143,806 is 551172622.
Find LCM of 749,581,143,806 with Prime Factorization
| 7 | 749, 581, 143, 806 |
| 13 | 107, 83, 143, 806 |
| 107, 83, 11, 62 |
Multiply the prime numbers at the bottom and the left side.
7 x 13 x 107 x 83 x 11 x 62 = 551172622
Therefore, the lowest common multiple of 749,581,143,806 is 551172622.
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.
749 x 581 x 143 x 806 = 50156708602
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.
749 : 1, 7, 107, 749
581 : 1, 7, 83, 581
143 : 1, 11, 13, 143
806 : 1, 2, 13, 26, 31, 62, 403, 806
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 749,581,143,806, is 1.
Now, the common factors can be found like this.
749:7x 107
581:7x 83
143:11x 13
806:2x 13x 31
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
7x 13 = 91
Therefore, the value for common factors is 91.
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 = 50156708602/(1x91)
LCM = 50156708602/91
LCM = 551172622
Thus, we can understand that the LCM of 749,581,143,806 is 551172622.
