Find LCM of 152,286,270,231,143 with Prime Factorization
2 | 152, 286, 270, 231, 143 |
3 | 76, 143, 135, 231, 143 |
11 | 76, 143, 45, 77, 143 |
13 | 76, 13, 45, 7, 13 |
76, 1, 45, 7, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 11 x 13 x 76 x 1 x 45 x 7 x 1 = 20540520
Therefore, the lowest common multiple of 152,286,270,231,143 is 20540520.
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.
152 x 286 x 270 x 231 x 143 = 387722855520
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.
152 : 1, 2, 4, 8, 19, 38, 76, 152
286 : 1, 2, 11, 13, 22, 26, 143, 286
270 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 27, 30, 45, 54, 90, 135, 270
231 : 1, 3, 7, 11, 21, 33, 77, 231
143 : 1, 11, 13, 143
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 152,286,270,231,143, is 1.
Now, the common factors can be found like this.
152:2x 2x 2x 19
286:2x 11x 13
270:2x 3x 3x 3x 5
231:3x 7x 11
143:11x 13
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 11x 13 = 18876
Therefore, the value for common factors is 18876.
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 = 387722855520/(1x18876)
LCM = 387722855520/18876
LCM = 20540520
Thus, we can understand that the LCM of 152,286,270,231,143 is 20540520.
