Given numbers are 487,867,340,942
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 487,867,340,942 is 1325799060.
Find LCM of 487,867,340,942 with Prime Factorization
| 2 | 487, 867, 340, 942 |
| 3 | 487, 867, 170, 471 |
| 17 | 487, 289, 170, 157 |
| 487, 17, 10, 157 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 17 x 487 x 17 x 10 x 157 = 1325799060
Therefore, the lowest common multiple of 487,867,340,942 is 1325799060.
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.
487 x 867 x 340 x 942 = 135231504120
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.
487 : 1, 487
867 : 1, 3, 17, 51, 289, 867
340 : 1, 2, 4, 5, 10, 17, 20, 34, 68, 85, 170, 340
942 : 1, 2, 3, 6, 157, 314, 471, 942
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 487,867,340,942, is 1.
Now, the common factors can be found like this.
487:487
867:3x 17x 17
340:2x 2x 5x 17
942:2x 3x 157
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 17 = 102
Therefore, the value for common factors is 102.
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 = 135231504120/(1x102)
LCM = 135231504120/102
LCM = 1325799060
Thus, we can understand that the LCM of 487,867,340,942 is 1325799060.
