Given numbers are 313,861,629,490
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 313,861,629,490 is 11865776790.
Find LCM of 313,861,629,490 with Prime Factorization
| 7 | 313, 861, 629, 490 |
| 313, 123, 629, 70 |
Multiply the prime numbers at the bottom and the left side.
7 x 313 x 123 x 629 x 70 = 11865776790
Therefore, the lowest common multiple of 313,861,629,490 is 11865776790.
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.
313 x 861 x 629 x 490 = 83060437530
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.
313 : 1, 313
861 : 1, 3, 7, 21, 41, 123, 287, 861
629 : 1, 17, 37, 629
490 : 1, 2, 5, 7, 10, 14, 35, 49, 70, 98, 245, 490
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 313,861,629,490, is 1.
Now, the common factors can be found like this.
313:313
861:3x 7x 41
629:17x 37
490:2x 5x 7x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
7 = 7
Therefore, the value for common factors is 7.
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 = 83060437530/(1x7)
LCM = 83060437530/7
LCM = 11865776790
Thus, we can understand that the LCM of 313,861,629,490 is 11865776790.
