Given numbers are 957,408,238,769
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 957,408,238,769 is 700608216.
Find LCM of 957,408,238,769 with Prime Factorization
| 2 | 957, 408, 238, 769 |
| 3 | 957, 204, 119, 769 |
| 17 | 319, 68, 119, 769 |
| 319, 4, 7, 769 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 17 x 319 x 4 x 7 x 769 = 700608216
Therefore, the lowest common multiple of 957,408,238,769 is 700608216.
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.
957 x 408 x 238 x 769 = 71462038032
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.
957 : 1, 3, 11, 29, 33, 87, 319, 957
408 : 1, 2, 3, 4, 6, 8, 12, 17, 24, 34, 51, 68, 102, 136, 204, 408
238 : 1, 2, 7, 14, 17, 34, 119, 238
769 : 1, 769
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 957,408,238,769, is 1.
Now, the common factors can be found like this.
957:3x 11x 29
408:2x 2x 2x 3x 17
238:2x 7x 17
769:769
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 17 = 102
Therefore, the value for common factors is 102.
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 = 71462038032/(1x102)
LCM = 71462038032/102
LCM = 700608216
Thus, we can understand that the LCM of 957,408,238,769 is 700608216.
