Given numbers are 843,707,513,931
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 843,707,513,931 is 713413197.
Find LCM of 843,707,513,931 with Prime Factorization
| 3 | 843, 707, 513, 931 |
| 7 | 281, 707, 171, 931 |
| 19 | 281, 101, 171, 133 |
| 281, 101, 9, 7 |
Multiply the prime numbers at the bottom and the left side.
3 x 7 x 19 x 281 x 101 x 9 x 7 = 713413197
Therefore, the lowest common multiple of 843,707,513,931 is 713413197.
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.
843 x 707 x 513 x 931 = 284651865603
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.
843 : 1, 3, 281, 843
707 : 1, 7, 101, 707
513 : 1, 3, 9, 19, 27, 57, 171, 513
931 : 1, 7, 19, 49, 133, 931
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 843,707,513,931, is 1.
Now, the common factors can be found like this.
843:3x 281
707:7x 101
513:3x 3x 3x 19
931:7x 7x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 7x 19 = 399
Therefore, the value for common factors is 399.
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 = 284651865603/(1x399)
LCM = 284651865603/399
LCM = 713413197
Thus, we can understand that the LCM of 843,707,513,931 is 713413197.
