Find LCM of 220,660,408,731 with Prime Factorization
2 | 220, 660, 408, 731 |
2 | 110, 330, 204, 731 |
3 | 55, 165, 102, 731 |
5 | 55, 55, 34, 731 |
11 | 11, 11, 34, 731 |
17 | 1, 1, 34, 731 |
1, 1, 2, 43 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 11 x 17 x 1 x 1 x 2 x 43 = 964920
Therefore, the lowest common multiple of 220,660,408,731 is 964920.
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.
220 x 660 x 408 x 731 = 43305609600
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.
220 : 1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, 220
660 : 1, 2, 3, 4, 5, 6, 10, 11, 12, 15, 20, 22, 30, 33, 44, 55, 60, 66, 110, 132, 165, 220, 330, 660
408 : 1, 2, 3, 4, 6, 8, 12, 17, 24, 34, 51, 68, 102, 136, 204, 408
731 : 1, 17, 43, 731
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 220,660,408,731, is 1.
Now, the common factors can be found like this.
220:2x 2x 5x 11
660:2x 2x 3x 5x 11
408:2x 2x 2x 3x 17
731:17x 43
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 3x 5x 11x 17 = 44880
Therefore, the value for common factors is 44880.
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 = 43305609600/(1x44880)
LCM = 43305609600/44880
LCM = 964920
Thus, we can understand that the LCM of 220,660,408,731 is 964920.
