Find LCM of 745,120,210,843,540 with Prime Factorization
| 2 | 745, 120, 210, 843, 540 |
| 2 | 745, 60, 105, 843, 270 |
| 3 | 745, 30, 105, 843, 135 |
| 5 | 745, 10, 35, 281, 45 |
| 149, 2, 7, 281, 9 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 149 x 2 x 7 x 281 x 9 = 316529640
Therefore, the lowest common multiple of 745,120,210,843,540 is 316529640.
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.
745 x 120 x 210 x 843 x 540 = 8546300280000
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.
745 : 1, 5, 149, 745
120 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, 120
210 : 1, 2, 3, 5, 6, 7, 10, 14, 15, 21, 30, 35, 42, 70, 105, 210
843 : 1, 3, 281, 843
540 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 27, 30, 36, 45, 54, 60, 90, 108, 135, 180, 270, 540
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 745,120,210,843,540, is 1.
Now, the common factors can be found like this.
745:5x 149
120:2x 2x 2x 3x 5
210:2x 3x 5x 7
843:3x 281
540:2x 2x 3x 3x 3x 5
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 2x 3x 3x 3x 5x 5x 5 = 27000
Therefore, the value for common factors is 27000.
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 = 8546300280000/(1x27000)
LCM = 8546300280000/27000
LCM = 316529640
Thus, we can understand that the LCM of 745,120,210,843,540 is 316529640.
