Find LCM of 561,868,407,444 with Prime Factorization
2 | 561, 868, 407, 444 |
2 | 561, 434, 407, 222 |
3 | 561, 217, 407, 111 |
11 | 187, 217, 407, 37 |
37 | 17, 217, 37, 37 |
17, 217, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 11 x 37 x 17 x 217 x 1 x 1 = 18017076
Therefore, the lowest common multiple of 561,868,407,444 is 18017076.
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.
561 x 868 x 407 x 444 = 87995399184
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.
561 : 1, 3, 11, 17, 33, 51, 187, 561
868 : 1, 2, 4, 7, 14, 28, 31, 62, 124, 217, 434, 868
407 : 1, 11, 37, 407
444 : 1, 2, 3, 4, 6, 12, 37, 74, 111, 148, 222, 444
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 561,868,407,444, is 1.
Now, the common factors can be found like this.
561:3x 11x 17
868:2x 2x 7x 31
407:11x 37
444:2x 2x 3x 37
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 11x 37 = 4884
Therefore, the value for common factors is 4884.
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 = 87995399184/(1x4884)
LCM = 87995399184/4884
LCM = 18017076
Thus, we can understand that the LCM of 561,868,407,444 is 18017076.
