The LCM of 266,133,480,40 is 63840.
Find LCM of 266,133,480,40 with Prime Factorization
| 2 | 266, 133, 480, 40 |
| 2 | 133, 133, 240, 20 |
| 2 | 133, 133, 120, 10 |
| 5 | 133, 133, 60, 5 |
| 7 | 133, 133, 12, 1 |
| 19 | 19, 19, 12, 1 |
| 1, 1, 12, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 5 x 7 x 19 x 1 x 1 x 12 x 1 = 63840
Therefore, the lowest common multiple of 266,133,480,40 is 63840.
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.
266 x 133 x 480 x 40 = 679257600
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.
266 : 1, 2, 7, 14, 19, 38, 133, 266
133 : 1, 7, 19, 133
480 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 32, 40, 48, 60, 80, 96, 120, 160, 240, 480
40 : 1, 2, 4, 5, 8, 10, 20, 40
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 266,133,480,40, is 1.
Now, the common factors can be found like this.
266:2x 7x 19
133:7x 19
480:2x 2x 2x 2x 2x 3x 5
40:2x 2x 2x 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 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 = 679257600/(1x10640)
LCM = 679257600/10640
LCM = 63840
Thus, we can understand that the LCM of 266,133,480,40 is 63840.
