Given numbers are 310,913,555,638
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 310,913,555,638 is 911073570.
Find LCM of 310,913,555,638 with Prime Factorization
| 2 | 310, 913, 555, 638 |
| 5 | 155, 913, 555, 319 |
| 11 | 31, 913, 111, 319 |
| 31, 83, 111, 29 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 11 x 31 x 83 x 111 x 29 = 911073570
Therefore, the lowest common multiple of 310,913,555,638 is 911073570.
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.
310 x 913 x 555 x 638 = 100218092700
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.
310 : 1, 2, 5, 10, 31, 62, 155, 310
913 : 1, 11, 83, 913
555 : 1, 3, 5, 15, 37, 111, 185, 555
638 : 1, 2, 11, 22, 29, 58, 319, 638
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 310,913,555,638, is 1.
Now, the common factors can be found like this.
310:2x 5x 31
913:11x 83
555:3x 5x 37
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 5x 11 = 110
Therefore, the value for common factors is 110.
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 = 100218092700/(1x110)
LCM = 100218092700/110
LCM = 911073570
Thus, we can understand that the LCM of 310,913,555,638 is 911073570.
