Given numbers are 642,428,592,148
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 642,428,592,148 is 190032.
Find LCM of 642,428,592,148 with Prime Factorization
| 2 | 642, 428, 592, 148 |
| 2 | 321, 214, 296, 74 |
| 37 | 321, 107, 148, 37 |
| 107 | 321, 107, 4, 1 |
| 3, 1, 4, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 37 x 107 x 3 x 1 x 4 x 1 = 190032
Therefore, the lowest common multiple of 642,428,592,148 is 190032.
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.
642 x 428 x 592 x 148 = 24074774016
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.
642 : 1, 2, 3, 6, 107, 214, 321, 642
428 : 1, 2, 4, 107, 214, 428
592 : 1, 2, 4, 8, 16, 37, 74, 148, 296, 592
148 : 1, 2, 4, 37, 74, 148
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 642,428,592,148, is 2.
Now, the common factors can be found like this.
642:2x 3x 107
428:2x 2x 107
592:2x 2x 2x 2x 37
148:2x 2x 37
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 2x 37x 107 = 63344
Therefore, the value for common factors is 63344.
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 = 24074774016/(2x63344)
LCM = 24074774016/126688
LCM = 190032
Thus, we can understand that the LCM of 642,428,592,148 is 190032.
