Given numbers are 428,676,311,767
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 428,676,311,767 is 1327219868.
Find LCM of 428,676,311,767 with Prime Factorization
2 | 428, 676, 311, 767 |
2 | 214, 338, 311, 767 |
13 | 107, 169, 311, 767 |
107, 13, 311, 59 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 13 x 107 x 13 x 311 x 59 = 1327219868
Therefore, the lowest common multiple of 428,676,311,767 is 1327219868.
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 676 x 311 x 767 = 69015433136
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
676 : 1, 2, 4, 13, 26, 52, 169, 338, 676
311 : 1, 311
767 : 1, 13, 59, 767
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 428,676,311,767, is 1.
Now, the common factors can be found like this.
428:2x 2x 107
676:2x 2x 13x 13
311:311
767:13x 59
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 13 = 52
Therefore, the value for common factors is 52.
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 = 69015433136/(1x52)
LCM = 69015433136/52
LCM = 1327219868
Thus, we can understand that the LCM of 428,676,311,767 is 1327219868.
