Find LCM of 157,915,685,807,269 with Prime Factorization
| 3 | 157, 915, 685, 807, 269 |
| 5 | 157, 305, 685, 269, 269 |
| 269 | 157, 61, 137, 269, 269 |
| 157, 61, 137, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 269 x 157 x 61 x 137 x 1 x 1 = 5294117715
Therefore, the lowest common multiple of 157,915,685,807,269 is 5294117715.
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.
157 x 915 x 685 x 807 x 269 = 21361764980025
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.
157 : 1, 157
915 : 1, 3, 5, 15, 61, 183, 305, 915
685 : 1, 5, 137, 685
807 : 1, 3, 269, 807
269 : 1, 269
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 157,915,685,807,269, is 1.
Now, the common factors can be found like this.
157:157
915:3x 5x 61
685:5x 137
807:3x 269
269:269
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 5x 269 = 4035
Therefore, the value for common factors is 4035.
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 = 21361764980025/(1x4035)
LCM = 21361764980025/4035
LCM = 5294117715
Thus, we can understand that the LCM of 157,915,685,807,269 is 5294117715.
