Given numbers are 391,115,717,863
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 391,115,717,863 is 1209697305.
Find LCM of 391,115,717,863 with Prime Factorization
23 | 391, 115, 717, 863 |
17, 5, 717, 863 |
Multiply the prime numbers at the bottom and the left side.
23 x 17 x 5 x 717 x 863 = 1209697305
Therefore, the lowest common multiple of 391,115,717,863 is 1209697305.
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.
391 x 115 x 717 x 863 = 27823038015
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.
391 : 1, 17, 23, 391
115 : 1, 5, 23, 115
717 : 1, 3, 239, 717
863 : 1, 863
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 391,115,717,863, is 1.
Now, the common factors can be found like this.
391:17x 23
115:5x 23
717:3x 239
863:863
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
23 = 23
Therefore, the value for common factors is 23.
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 = 27823038015/(1x23)
LCM = 27823038015/23
LCM = 1209697305
Thus, we can understand that the LCM of 391,115,717,863 is 1209697305.
