Find LCM of 151,840,675,972 with Prime Factorization
| 2 | 151, 840, 675, 972 |
| 2 | 151, 420, 675, 486 |
| 3 | 151, 210, 675, 243 |
| 3 | 151, 70, 225, 81 |
| 3 | 151, 70, 75, 27 |
| 5 | 151, 70, 25, 9 |
| 151, 14, 5, 9 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 3 x 5 x 151 x 14 x 5 x 9 = 51370200
Therefore, the lowest common multiple of 151,840,675,972 is 51370200.
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.
151 x 840 x 675 x 972 = 83219724000
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.
151 : 1, 151
840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840
675 : 1, 3, 5, 9, 15, 25, 27, 45, 75, 135, 225, 675
972 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 81, 108, 162, 243, 324, 486, 972
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 151,840,675,972, is 1.
Now, the common factors can be found like this.
151:151
840:2x 2x 2x 3x 5x 7
675:3x 3x 3x 5x 5
972:2x 2x 3x 3x 3x 3x 3
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 5 = 1620
Therefore, the value for common factors is 1620.
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 = 83219724000/(1x1620)
LCM = 83219724000/1620
LCM = 51370200
Thus, we can understand that the LCM of 151,840,675,972 is 51370200.
