Given numbers are 713,138,803,957
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 713,138,803,957 is 99621786.
Find LCM of 713,138,803,957 with Prime Factorization
| 3 | 713, 138, 803, 957 |
| 11 | 713, 46, 803, 319 |
| 23 | 713, 46, 73, 29 |
| 31, 2, 73, 29 |
Multiply the prime numbers at the bottom and the left side.
3 x 11 x 23 x 31 x 2 x 73 x 29 = 99621786
Therefore, the lowest common multiple of 713,138,803,957 is 99621786.
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.
713 x 138 x 803 x 957 = 75612935574
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.
713 : 1, 23, 31, 713
138 : 1, 2, 3, 6, 23, 46, 69, 138
803 : 1, 11, 73, 803
957 : 1, 3, 11, 29, 33, 87, 319, 957
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 713,138,803,957, is 1.
Now, the common factors can be found like this.
713:23x 31
138:2x 3x 23
803:11x 73
957:3x 11x 29
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 11x 23 = 759
Therefore, the value for common factors is 759.
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 = 75612935574/(1x759)
LCM = 75612935574/759
LCM = 99621786
Thus, we can understand that the LCM of 713,138,803,957 is 99621786.
