Given numbers are 455,133,285,736
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 455,133,285,736 is 19088160.
Find LCM of 455,133,285,736 with Prime Factorization
5 | 455, 133, 285, 736 |
7 | 91, 133, 57, 736 |
19 | 13, 19, 57, 736 |
13, 1, 3, 736 |
Multiply the prime numbers at the bottom and the left side.
5 x 7 x 19 x 13 x 1 x 3 x 736 = 19088160
Therefore, the lowest common multiple of 455,133,285,736 is 19088160.
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.
455 x 133 x 285 x 736 = 12693626400
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.
455 : 1, 5, 7, 13, 35, 65, 91, 455
133 : 1, 7, 19, 133
285 : 1, 3, 5, 15, 19, 57, 95, 285
736 : 1, 2, 4, 8, 16, 23, 32, 46, 92, 184, 368, 736
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 455,133,285,736, is 1.
Now, the common factors can be found like this.
455:5x 7x 13
133:7x 19
285:3x 5x 19
736:2x 2x 2x 2x 2x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5x 7x 19 = 665
Therefore, the value for common factors is 665.
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 = 12693626400/(1x665)
LCM = 12693626400/665
LCM = 19088160
Thus, we can understand that the LCM of 455,133,285,736 is 19088160.
