Given numbers are 140,608,798,751
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 140,608,798,751 is 47943840.
Find LCM of 140,608,798,751 with Prime Factorization
| 2 | 140, 608, 798, 751 |
| 2 | 70, 304, 399, 751 |
| 7 | 35, 152, 399, 751 |
| 19 | 5, 152, 57, 751 |
| 5, 8, 3, 751 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 19 x 5 x 8 x 3 x 751 = 47943840
Therefore, the lowest common multiple of 140,608,798,751 is 47943840.
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.
140 x 608 x 798 x 751 = 51012245760
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.
140 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 70, 140
608 : 1, 2, 4, 8, 16, 19, 32, 38, 76, 152, 304, 608
798 : 1, 2, 3, 6, 7, 14, 19, 21, 38, 42, 57, 114, 133, 266, 399, 798
751 : 1, 751
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 140,608,798,751, is 1.
Now, the common factors can be found like this.
140:2x 2x 5x 7
608:2x 2x 2x 2x 2x 19
798:2x 3x 7x 19
751:751
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 7x 19 = 1064
Therefore, the value for common factors is 1064.
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 = 51012245760/(1x1064)
LCM = 51012245760/1064
LCM = 47943840
Thus, we can understand that the LCM of 140,608,798,751 is 47943840.
