Find LCM of 108,576,432,778 with Prime Factorization
| 2 | 108, 576, 432, 778 |
| 2 | 54, 288, 216, 389 |
| 2 | 27, 144, 108, 389 |
| 2 | 27, 72, 54, 389 |
| 3 | 27, 36, 27, 389 |
| 3 | 9, 12, 9, 389 |
| 3 | 3, 4, 3, 389 |
| 1, 4, 1, 389 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 3 x 3 x 3 x 1 x 4 x 1 x 389 = 672192
Therefore, the lowest common multiple of 108,576,432,778 is 672192.
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.
108 x 576 x 432 x 778 = 20907859968
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.
108 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 108
576 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 32, 36, 48, 64, 72, 96, 144, 192, 288, 576
432 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 27, 36, 48, 54, 72, 108, 144, 216, 432
778 : 1, 2, 389, 778
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 108,576,432,778, is 2.
Now, the common factors can be found like this.
108:2x 2x 3x 3x 3
576:2x 2x 2x 2x 2x 2x 3x 3
432:2x 2x 2x 2x 3x 3x 3
778:2x 389
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 2x 2x 2x 3x 3x 3x 3x 3 = 15552
Therefore, the value for common factors is 15552.
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 = 20907859968/(2x15552)
LCM = 20907859968/31104
LCM = 672192
Thus, we can understand that the LCM of 108,576,432,778 is 672192.
