Given numbers are 370,208,782,884,921
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 370,208,782,884,921 is 13857071280.
Find LCM of 370,208,782,884,921 with Prime Factorization
| 2 | 370, 208, 782, 884, 921 |
| 2 | 185, 104, 391, 442, 921 |
| 13 | 185, 52, 391, 221, 921 |
| 17 | 185, 4, 391, 17, 921 |
| 185, 4, 23, 1, 921 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 13 x 17 x 185 x 4 x 23 x 1 x 921 = 13857071280
Therefore, the lowest common multiple of 370,208,782,884,921 is 13857071280.
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.
370 x 208 x 782 x 884 x 921 = 48998604046080
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.
370 : 1, 2, 5, 10, 37, 74, 185, 370
208 : 1, 2, 4, 8, 13, 16, 26, 52, 104, 208
782 : 1, 2, 17, 23, 34, 46, 391, 782
884 : 1, 2, 4, 13, 17, 26, 34, 52, 68, 221, 442, 884
921 : 1, 3, 307, 921
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 370,208,782,884,921, is 1.
Now, the common factors can be found like this.
370:2x 5x 37
208:2x 2x 2x 2x 13
782:2x 17x 23
884:2x 2x 13x 17
921:3x 307
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 2x 2x 13x 17 = 3536
Therefore, the value for common factors is 3536.
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 = 48998604046080/(1x3536)
LCM = 48998604046080/3536
LCM = 13857071280
Thus, we can understand that the LCM of 370,208,782,884,921 is 13857071280.
