Find LCM of 642,112,411,423,270 with Prime Factorization
2 | 642, 112, 411, 423, 270 |
3 | 321, 56, 411, 423, 135 |
3 | 107, 56, 137, 141, 45 |
107, 56, 137, 47, 15 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 107 x 56 x 137 x 47 x 15 = 10417271760
Therefore, the lowest common multiple of 642,112,411,423,270 is 10417271760.
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.
642 x 112 x 411 x 423 x 270 = 3375196050240
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.
642 : 1, 2, 3, 6, 107, 214, 321, 642
112 : 1, 2, 4, 7, 8, 14, 16, 28, 56, 112
411 : 1, 3, 137, 411
423 : 1, 3, 9, 47, 141, 423
270 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 27, 30, 45, 54, 90, 135, 270
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 642,112,411,423,270, is 1.
Now, the common factors can be found like this.
642:2x 3x 107
112:2x 2x 2x 2x 7
411:3x 137
423:3x 3x 47
270:2x 3x 3x 3x 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 3 = 324
Therefore, the value for common factors is 324.
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 = 3375196050240/(1x324)
LCM = 3375196050240/324
LCM = 10417271760
Thus, we can understand that the LCM of 642,112,411,423,270 is 10417271760.
