Given numbers are 100,870,768,346,809
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 100,870,768,346,809 is 77928057600.
Find LCM of 100,870,768,346,809 with Prime Factorization
| 2 | 100, 870, 768, 346, 809 |
| 2 | 50, 435, 384, 173, 809 |
| 3 | 25, 435, 192, 173, 809 |
| 5 | 25, 145, 64, 173, 809 |
| 5, 29, 64, 173, 809 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 5 x 29 x 64 x 173 x 809 = 77928057600
Therefore, the lowest common multiple of 100,870,768,346,809 is 77928057600.
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.
100 x 870 x 768 x 346 x 809 = 18702733824000
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.
100 : 1, 2, 4, 5, 10, 20, 25, 50, 100
870 : 1, 2, 3, 5, 6, 10, 15, 29, 30, 58, 87, 145, 174, 290, 435, 870
768 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 128, 192, 256, 384, 768
346 : 1, 2, 173, 346
809 : 1, 809
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 100,870,768,346,809, is 1.
Now, the common factors can be found like this.
100:2x 2x 5x 5
870:2x 3x 5x 29
768:2x 2x 2x 2x 2x 2x 2x 2x 3
346:2x 173
809:809
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 2x 3x 5 = 240
Therefore, the value for common factors is 240.
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 = 18702733824000/(1x240)
LCM = 18702733824000/240
LCM = 77928057600
Thus, we can understand that the LCM of 100,870,768,346,809 is 77928057600.
