Given numbers are 105,562,247,684,823
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 105,562,247,684,823 is 71973670860.
Find LCM of 105,562,247,684,823 with Prime Factorization
| 2 | 105, 562, 247, 684, 823 |
| 3 | 105, 281, 247, 342, 823 |
| 19 | 35, 281, 247, 114, 823 |
| 35, 281, 13, 6, 823 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 19 x 35 x 281 x 13 x 6 x 823 = 71973670860
Therefore, the lowest common multiple of 105,562,247,684,823 is 71973670860.
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.
105 x 562 x 247 x 684 x 823 = 8204998478040
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.
105 : 1, 3, 5, 7, 15, 21, 35, 105
562 : 1, 2, 281, 562
247 : 1, 13, 19, 247
684 : 1, 2, 3, 4, 6, 9, 12, 18, 19, 36, 38, 57, 76, 114, 171, 228, 342, 684
823 : 1, 823
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 105,562,247,684,823, is 1.
Now, the common factors can be found like this.
105:3x 5x 7
562:2x 281
247:13x 19
684:2x 2x 3x 3x 19
823:823
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 19 = 114
Therefore, the value for common factors is 114.
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 = 8204998478040/(1x114)
LCM = 8204998478040/114
LCM = 71973670860
Thus, we can understand that the LCM of 105,562,247,684,823 is 71973670860.
