Find LCM of 140,823,108,571,747 with Prime Factorization
| 2 | 140, 823, 108, 571, 747 |
| 2 | 70, 823, 54, 571, 747 |
| 3 | 35, 823, 27, 571, 747 |
| 3 | 35, 823, 9, 571, 249 |
| 35, 823, 3, 571, 83 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 35 x 823 x 3 x 571 x 83 = 147436779420
Therefore, the lowest common multiple of 140,823,108,571,747 is 147436779420.
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.
140 x 823 x 108 x 571 x 747 = 5307724059120
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.
140 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 70, 140
823 : 1, 823
108 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 108
571 : 1, 571
747 : 1, 3, 9, 83, 249, 747
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 140,823,108,571,747, is 1.
Now, the common factors can be found like this.
140:2x 2x 5x 7
823:823
108:2x 2x 3x 3x 3
571:571
747:3x 3x 83
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 3x 3 = 36
Therefore, the value for common factors is 36.
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 = 5307724059120/(1x36)
LCM = 5307724059120/36
LCM = 147436779420
Thus, we can understand that the LCM of 140,823,108,571,747 is 147436779420.
