Given numbers are 286,143,231,491
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 286,143,231,491 is 2948946.
Find LCM of 286,143,231,491 with Prime Factorization
11 | 286, 143, 231, 491 |
13 | 26, 13, 21, 491 |
2, 1, 21, 491 |
Multiply the prime numbers at the bottom and the left side.
11 x 13 x 2 x 1 x 21 x 491 = 2948946
Therefore, the lowest common multiple of 286,143,231,491 is 2948946.
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.
286 x 143 x 231 x 491 = 4638692058
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.
286 : 1, 2, 11, 13, 22, 26, 143, 286
143 : 1, 11, 13, 143
231 : 1, 3, 7, 11, 21, 33, 77, 231
491 : 1, 491
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 286,143,231,491, is 1.
Now, the common factors can be found like this.
286:2x 11x 13
143:11x 13
231:3x 7x 11
491:491
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
11x 11x 13 = 1573
Therefore, the value for common factors is 1573.
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 = 4638692058/(1x1573)
LCM = 4638692058/1573
LCM = 2948946
Thus, we can understand that the LCM of 286,143,231,491 is 2948946.
