Find LCM of 128,425,345,429,472 with Prime Factorization
| 2 | 128, 425, 345, 429, 472 |
| 2 | 64, 425, 345, 429, 236 |
| 2 | 32, 425, 345, 429, 118 |
| 3 | 16, 425, 345, 429, 59 |
| 5 | 16, 425, 115, 143, 59 |
| 16, 85, 23, 143, 59 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 5 x 16 x 85 x 23 x 143 x 59 = 31669123200
Therefore, the lowest common multiple of 128,425,345,429,472 is 31669123200.
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.
128 x 425 x 345 x 429 x 472 = 3800294784000
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.
128 : 1, 2, 4, 8, 16, 32, 64, 128
425 : 1, 5, 17, 25, 85, 425
345 : 1, 3, 5, 15, 23, 69, 115, 345
429 : 1, 3, 11, 13, 33, 39, 143, 429
472 : 1, 2, 4, 8, 59, 118, 236, 472
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 128,425,345,429,472, is 1.
Now, the common factors can be found like this.
128:2x 2x 2x 2x 2x 2x 2
425:5x 5x 17
345:3x 5x 23
429:3x 11x 13
472:2x 2x 2x 59
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 5 = 120
Therefore, the value for common factors is 120.
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 = 3800294784000/(1x120)
LCM = 3800294784000/120
LCM = 31669123200
Thus, we can understand that the LCM of 128,425,345,429,472 is 31669123200.
