Given numbers are 991,770,815,199
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 991,770,815,199 is 24751701590.
Find LCM of 991,770,815,199 with Prime Factorization
| 5 | 991, 770, 815, 199 |
| 991, 154, 163, 199 |
Multiply the prime numbers at the bottom and the left side.
5 x 991 x 154 x 163 x 199 = 24751701590
Therefore, the lowest common multiple of 991,770,815,199 is 24751701590.
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 770 x 815 x 199 = 123758507950
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
770 : 1, 2, 5, 7, 10, 11, 14, 22, 35, 55, 70, 77, 110, 154, 385, 770
815 : 1, 5, 163, 815
199 : 1, 199
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 991,770,815,199, is 1.
Now, the common factors can be found like this.
991:991
770:2x 5x 7x 11
815:5x 163
199:199
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5 = 5
Therefore, the value for common factors is 5.
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 = 123758507950/(1x5)
LCM = 123758507950/5
LCM = 24751701590
Thus, we can understand that the LCM of 991,770,815,199 is 24751701590.
