Given numbers are 428,846,428,741
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 428,846,428,741 is 44717868.
Find LCM of 428,846,428,741 with Prime Factorization
| 2 | 428, 846, 428, 741 |
| 2 | 214, 423, 214, 741 |
| 3 | 107, 423, 107, 741 |
| 107 | 107, 141, 107, 247 |
| 1, 141, 1, 247 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 107 x 1 x 141 x 1 x 247 = 44717868
Therefore, the lowest common multiple of 428,846,428,741 is 44717868.
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 846 x 428 x 741 = 114835485024
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
846 : 1, 2, 3, 6, 9, 18, 47, 94, 141, 282, 423, 846
428 : 1, 2, 4, 107, 214, 428
741 : 1, 3, 13, 19, 39, 57, 247, 741
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 428,846,428,741, is 1.
Now, the common factors can be found like this.
428:2x 2x 107
846:2x 3x 3x 47
428:2x 2x 107
741:3x 13x 19
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 2x 3x 107 = 2568
Therefore, the value for common factors is 2568.
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 = 114835485024/(1x2568)
LCM = 114835485024/2568
LCM = 44717868
Thus, we can understand that the LCM of 428,846,428,741 is 44717868.
