Given numbers are 251,455,945,207
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 251,455,945,207 is 70921305.
Find LCM of 251,455,945,207 with Prime Factorization
| 3 | 251, 455, 945, 207 |
| 3 | 251, 455, 315, 69 |
| 5 | 251, 455, 105, 23 |
| 7 | 251, 91, 21, 23 |
| 251, 13, 3, 23 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 5 x 7 x 251 x 13 x 3 x 23 = 70921305
Therefore, the lowest common multiple of 251,455,945,207 is 70921305.
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.
251 x 455 x 945 x 207 = 22340211075
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.
251 : 1, 251
455 : 1, 5, 7, 13, 35, 65, 91, 455
945 : 1, 3, 5, 7, 9, 15, 21, 27, 35, 45, 63, 105, 135, 189, 315, 945
207 : 1, 3, 9, 23, 69, 207
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 251,455,945,207, is 1.
Now, the common factors can be found like this.
251:251
455:5x 7x 13
945:3x 3x 3x 5x 7
207:3x 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.
3x 3x 5x 7 = 315
Therefore, the value for common factors is 315.
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 = 22340211075/(1x315)
LCM = 22340211075/315
LCM = 70921305
Thus, we can understand that the LCM of 251,455,945,207 is 70921305.
