Given numbers are 991,787,858,506,965
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 991,787,858,506,965 is 14852201205270.
Find LCM of 991,787,858,506,965 with Prime Factorization
| 2 | 991, 787, 858, 506, 965 |
| 11 | 991, 787, 429, 253, 965 |
| 991, 787, 39, 23, 965 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 991 x 787 x 39 x 23 x 965 = 14852201205270
Therefore, the lowest common multiple of 991,787,858,506,965 is 14852201205270.
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.
991 x 787 x 858 x 506 x 965 = 326748426515940
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.
991 : 1, 991
787 : 1, 787
858 : 1, 2, 3, 6, 11, 13, 22, 26, 33, 39, 66, 78, 143, 286, 429, 858
506 : 1, 2, 11, 22, 23, 46, 253, 506
965 : 1, 5, 193, 965
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 991,787,858,506,965, is 1.
Now, the common factors can be found like this.
991:991
787:787
858:2x 3x 11x 13
506:2x 11x 23
965:5x 193
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 11 = 22
Therefore, the value for common factors is 22.
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 = 326748426515940/(1x22)
LCM = 326748426515940/22
LCM = 14852201205270
Thus, we can understand that the LCM of 991,787,858,506,965 is 14852201205270.
