Given numbers are 280,679,507,259,138
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 280,679,507,259,138 is 11718372120.
Find LCM of 280,679,507,259,138 with Prime Factorization
| 2 | 280, 679, 507, 259, 138 |
| 3 | 140, 679, 507, 259, 69 |
| 7 | 140, 679, 169, 259, 23 |
| 20, 97, 169, 37, 23 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 20 x 97 x 169 x 37 x 23 = 11718372120
Therefore, the lowest common multiple of 280,679,507,259,138 is 11718372120.
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.
280 x 679 x 507 x 259 x 138 = 3445201403280
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.
280 : 1, 2, 4, 5, 7, 8, 10, 14, 20, 28, 35, 40, 56, 70, 140, 280
679 : 1, 7, 97, 679
507 : 1, 3, 13, 39, 169, 507
259 : 1, 7, 37, 259
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 280,679,507,259,138, is 1.
Now, the common factors can be found like this.
280:2x 2x 2x 5x 7
679:7x 97
507:3x 13x 13
259:7x 37
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 3x 7x 7 = 294
Therefore, the value for common factors is 294.
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 = 3445201403280/(1x294)
LCM = 3445201403280/294
LCM = 11718372120
Thus, we can understand that the LCM of 280,679,507,259,138 is 11718372120.
