Find LCM of 445,972,432,675 with Prime Factorization
| 2 | 445, 972, 432, 675 |
| 2 | 445, 486, 216, 675 |
| 3 | 445, 243, 108, 675 |
| 3 | 445, 81, 36, 225 |
| 3 | 445, 27, 12, 75 |
| 5 | 445, 9, 4, 25 |
| 89, 9, 4, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 3 x 5 x 89 x 9 x 4 x 5 = 8650800
Therefore, the lowest common multiple of 445,972,432,675 is 8650800.
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.
445 x 972 x 432 x 675 = 126128664000
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.
445 : 1, 5, 89, 445
972 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 81, 108, 162, 243, 324, 486, 972
432 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 27, 36, 48, 54, 72, 108, 144, 216, 432
675 : 1, 3, 5, 9, 15, 25, 27, 45, 75, 135, 225, 675
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 445,972,432,675, is 1.
Now, the common factors can be found like this.
445:5x 89
972:2x 2x 3x 3x 3x 3x 3
432:2x 2x 2x 2x 3x 3x 3
675:3x 3x 3x 5x 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 3x 3x 3x 3x 3x 3x 5 = 14580
Therefore, the value for common factors is 14580.
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 = 126128664000/(1x14580)
LCM = 126128664000/14580
LCM = 8650800
Thus, we can understand that the LCM of 445,972,432,675 is 8650800.
