Given numbers are 622,414,870,249,138
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 622,414,870,249,138 is 1549554390.
Find LCM of 622,414,870,249,138 with Prime Factorization
| 2 | 622, 414, 870, 249, 138 |
| 3 | 311, 207, 435, 249, 69 |
| 23 | 311, 23, 145, 83, 69 |
| 311, 1, 145, 83, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 23 x 311 x 1 x 145 x 83 x 3 = 1549554390
Therefore, the lowest common multiple of 622,414,870,249,138 is 1549554390.
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.
622 x 414 x 870 x 249 x 138 = 7698186209520
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.
622 : 1, 2, 311, 622
414 : 1, 2, 3, 6, 9, 18, 23, 46, 69, 138, 207, 414
870 : 1, 2, 3, 5, 6, 10, 15, 29, 30, 58, 87, 145, 174, 290, 435, 870
249 : 1, 3, 83, 249
138 : 1, 2, 3, 6, 23, 46, 69, 138
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 622,414,870,249,138, is 1.
Now, the common factors can be found like this.
622:2x 311
414:2x 3x 3x 23
870:2x 3x 5x 29
249:3x 83
138:2x 3x 23
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 3x 3x 3x 23 = 4968
Therefore, the value for common factors is 4968.
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 = 7698186209520/(1x4968)
LCM = 7698186209520/4968
LCM = 1549554390
Thus, we can understand that the LCM of 622,414,870,249,138 is 1549554390.
