Given numbers are 257,849,994,852,687
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 257,849,994,852,687 is 99332799636.
Find LCM of 257,849,994,852,687 with Prime Factorization
| 2 | 257, 849, 994, 852, 687 |
| 3 | 257, 849, 497, 426, 687 |
| 71 | 257, 283, 497, 142, 229 |
| 257, 283, 7, 2, 229 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 71 x 257 x 283 x 7 x 2 x 229 = 99332799636
Therefore, the lowest common multiple of 257,849,994,852,687 is 99332799636.
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.
257 x 849 x 994 x 852 x 687 = 126947317934808
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.
257 : 1, 257
849 : 1, 3, 283, 849
994 : 1, 2, 7, 14, 71, 142, 497, 994
852 : 1, 2, 3, 4, 6, 12, 71, 142, 213, 284, 426, 852
687 : 1, 3, 229, 687
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 257,849,994,852,687, is 1.
Now, the common factors can be found like this.
257:257
849:3x 283
994:2x 7x 71
852:2x 2x 3x 71
687:3x 229
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 71 = 1278
Therefore, the value for common factors is 1278.
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 = 126947317934808/(1x1278)
LCM = 126947317934808/1278
LCM = 99332799636
Thus, we can understand that the LCM of 257,849,994,852,687 is 99332799636.
