Given numbers are 646,484,703
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 646,484,703 is 5784284.
Find LCM of 646,484,703 with Prime Factorization
| 2 | 646, 484, 703 |
| 19 | 323, 242, 703 |
| 17, 242, 37 |
Multiply the prime numbers at the bottom and the left side.
2 x 19 x 17 x 242 x 37 = 5784284
Therefore, the lowest common multiple of 646,484,703 is 5784284.
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.
646 x 484 x 703 = 219802792
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.
646 : 1, 2, 17, 19, 34, 38, 323, 646
484 : 1, 2, 4, 11, 22, 44, 121, 242, 484
703 : 1, 19, 37, 703
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 646,484,703, is 1.
Now, the common factors can be found like this.
646:2x 17x 19
484:2x 2x 11x 11
703:19x 37
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 19 = 38
Therefore, the value for common factors is 38.
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 = 219802792/(1x38)
LCM = 219802792/38
LCM = 5784284
Thus, we can understand that the LCM of 646,484,703 is 5784284.
