Given numbers are 428,211,834,771
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 428,211,834,771 is 9678218052.
Find LCM of 428,211,834,771 with Prime Factorization
2 | 428, 211, 834, 771 |
3 | 214, 211, 417, 771 |
214, 211, 139, 257 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 214 x 211 x 139 x 257 = 9678218052
Therefore, the lowest common multiple of 428,211,834,771 is 9678218052.
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.
428 x 211 x 834 x 771 = 58069308312
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.
428 : 1, 2, 4, 107, 214, 428
211 : 1, 211
834 : 1, 2, 3, 6, 139, 278, 417, 834
771 : 1, 3, 257, 771
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 428,211,834,771, is 1.
Now, the common factors can be found like this.
428:2x 2x 107
211:211
834:2x 3x 139
771:3x 257
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3 = 6
Therefore, the value for common factors is 6.
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 = 58069308312/(1x6)
LCM = 58069308312/6
LCM = 9678218052
Thus, we can understand that the LCM of 428,211,834,771 is 9678218052.
