Given numbers are 991,949,407,803
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 991,949,407,803 is 382766813.
Find LCM of 991,949,407,803 with Prime Factorization
| 11 | 991, 949, 407, 803 |
| 73 | 991, 949, 37, 73 |
| 991, 13, 37, 1 |
Multiply the prime numbers at the bottom and the left side.
11 x 73 x 991 x 13 x 37 x 1 = 382766813
Therefore, the lowest common multiple of 991,949,407,803 is 382766813.
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 949 x 407 x 803 = 307361750839
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
949 : 1, 13, 73, 949
407 : 1, 11, 37, 407
803 : 1, 11, 73, 803
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 991,949,407,803, is 1.
Now, the common factors can be found like this.
991:991
949:13x 73
407:11x 37
803:11x 73
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
11x 73 = 803
Therefore, the value for common factors is 803.
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 = 307361750839/(1x803)
LCM = 307361750839/803
LCM = 382766813
Thus, we can understand that the LCM of 991,949,407,803 is 382766813.
