Given numbers are 678,817,903,283
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 678,817,903,283 is 1097327406.
Find LCM of 678,817,903,283 with Prime Factorization
| 3 | 678, 817, 903, 283 |
| 43 | 226, 817, 301, 283 |
| 226, 19, 7, 283 |
Multiply the prime numbers at the bottom and the left side.
3 x 43 x 226 x 19 x 7 x 283 = 1097327406
Therefore, the lowest common multiple of 678,817,903,283 is 1097327406.
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.
678 x 817 x 903 x 283 = 141555235374
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.
678 : 1, 2, 3, 6, 113, 226, 339, 678
817 : 1, 19, 43, 817
903 : 1, 3, 7, 21, 43, 129, 301, 903
283 : 1, 283
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 678,817,903,283, is 1.
Now, the common factors can be found like this.
678:2x 3x 113
817:19x 43
903:3x 7x 43
283:283
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 43 = 129
Therefore, the value for common factors is 129.
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 = 141555235374/(1x129)
LCM = 141555235374/129
LCM = 1097327406
Thus, we can understand that the LCM of 678,817,903,283 is 1097327406.
