Find LCM of 200,665,556,646,154 with Prime Factorization
| 2 | 200, 665, 556, 646, 154 |
| 2 | 100, 665, 278, 323, 77 |
| 5 | 50, 665, 139, 323, 77 |
| 7 | 10, 133, 139, 323, 77 |
| 19 | 10, 19, 139, 323, 11 |
| 10, 1, 139, 17, 11 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 7 x 19 x 10 x 1 x 139 x 17 x 11 = 691413800
Therefore, the lowest common multiple of 200,665,556,646,154 is 691413800.
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.
200 x 665 x 556 x 646 x 154 = 7356642832000
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.
200 : 1, 2, 4, 5, 8, 10, 20, 25, 40, 50, 100, 200
665 : 1, 5, 7, 19, 35, 95, 133, 665
556 : 1, 2, 4, 139, 278, 556
646 : 1, 2, 17, 19, 34, 38, 323, 646
154 : 1, 2, 7, 11, 14, 22, 77, 154
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 200,665,556,646,154, is 1.
Now, the common factors can be found like this.
200:2x 2x 2x 5x 5
665:5x 7x 19
556:2x 2x 139
646:2x 17x 19
154:2x 7x 11
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 5x 7x 19 = 10640
Therefore, the value for common factors is 10640.
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 = 7356642832000/(1x10640)
LCM = 7356642832000/10640
LCM = 691413800
Thus, we can understand that the LCM of 200,665,556,646,154 is 691413800.
