Given numbers are 432,551,146,146,145
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 432,551,146,146,145 is 86881680.
Find LCM of 432,551,146,146,145 with Prime Factorization
| 2 | 432, 551, 146, 146, 145 |
| 29 | 216, 551, 73, 73, 145 |
| 73 | 216, 19, 73, 73, 5 |
| 216, 19, 1, 1, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 29 x 73 x 216 x 19 x 1 x 1 x 5 = 86881680
Therefore, the lowest common multiple of 432,551,146,146,145 is 86881680.
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.
432 x 551 x 146 x 146 x 145 = 735714066240
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.
432 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 27, 36, 48, 54, 72, 108, 144, 216, 432
551 : 1, 19, 29, 551
146 : 1, 2, 73, 146
146 : 1, 2, 73, 146
145 : 1, 5, 29, 145
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 432,551,146,146,145, is 1.
Now, the common factors can be found like this.
432:2x 2x 2x 2x 3x 3x 3
551:19x 29
146:2x 73
146:2x 73
145:5x 29
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 29x 73 = 8468
Therefore, the value for common factors is 8468.
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 = 735714066240/(1x8468)
LCM = 735714066240/8468
LCM = 86881680
Thus, we can understand that the LCM of 432,551,146,146,145 is 86881680.
