Given numbers are 949,921,910,898,820
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 949,921,910,898,820 is 2252599980540.
Find LCM of 949,921,910,898,820 with Prime Factorization
| 2 | 949, 921, 910, 898, 820 |
| 5 | 949, 921, 455, 449, 410 |
| 13 | 949, 921, 91, 449, 82 |
| 73, 921, 7, 449, 82 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 13 x 73 x 921 x 7 x 449 x 82 = 2252599980540
Therefore, the lowest common multiple of 949,921,910,898,820 is 2252599980540.
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.
949 x 921 x 910 x 898 x 820 = 585675994940400
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.
949 : 1, 13, 73, 949
921 : 1, 3, 307, 921
910 : 1, 2, 5, 7, 10, 13, 14, 26, 35, 65, 70, 91, 130, 182, 455, 910
898 : 1, 2, 449, 898
820 : 1, 2, 4, 5, 10, 20, 41, 82, 164, 205, 410, 820
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 949,921,910,898,820, is 1.
Now, the common factors can be found like this.
949:13x 73
921:3x 307
910:2x 5x 7x 13
898:2x 449
820:2x 2x 5x 41
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 5x 13 = 260
Therefore, the value for common factors is 260.
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 = 585675994940400/(1x260)
LCM = 585675994940400/260
LCM = 2252599980540
Thus, we can understand that the LCM of 949,921,910,898,820 is 2252599980540.
