Given numbers are 403,978,858,247
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 403,978,858,247 is 82374006.
Find LCM of 403,978,858,247 with Prime Factorization
| 2 | 403, 978, 858, 247 |
| 3 | 403, 489, 429, 247 |
| 13 | 403, 163, 143, 247 |
| 31, 163, 11, 19 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 13 x 31 x 163 x 11 x 19 = 82374006
Therefore, the lowest common multiple of 403,978,858,247 is 82374006.
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.
403 x 978 x 858 x 247 = 83527242084
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.
403 : 1, 13, 31, 403
978 : 1, 2, 3, 6, 163, 326, 489, 978
858 : 1, 2, 3, 6, 11, 13, 22, 26, 33, 39, 66, 78, 143, 286, 429, 858
247 : 1, 13, 19, 247
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 403,978,858,247, is 1.
Now, the common factors can be found like this.
403:13x 31
978:2x 3x 163
858:2x 3x 11x 13
247:13x 19
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 13x 13 = 1014
Therefore, the value for common factors is 1014.
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 = 83527242084/(1x1014)
LCM = 83527242084/1014
LCM = 82374006
Thus, we can understand that the LCM of 403,978,858,247 is 82374006.
