Given numbers are 340,213,781,357
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 340,213,781,357 is 5576340.
Find LCM of 340,213,781,357 with Prime Factorization
| 3 | 340, 213, 781, 357 |
| 17 | 340, 71, 781, 119 |
| 71 | 20, 71, 781, 7 |
| 20, 1, 11, 7 |
Multiply the prime numbers at the bottom and the left side.
3 x 17 x 71 x 20 x 1 x 11 x 7 = 5576340
Therefore, the lowest common multiple of 340,213,781,357 is 5576340.
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.
340 x 213 x 781 x 357 = 20191927140
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.
340 : 1, 2, 4, 5, 10, 17, 20, 34, 68, 85, 170, 340
213 : 1, 3, 71, 213
781 : 1, 11, 71, 781
357 : 1, 3, 7, 17, 21, 51, 119, 357
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 340,213,781,357, is 1.
Now, the common factors can be found like this.
340:2x 2x 5x 17
213:3x 71
781:11x 71
357:3x 7x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 17x 71 = 3621
Therefore, the value for common factors is 3621.
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 = 20191927140/(1x3621)
LCM = 20191927140/3621
LCM = 5576340
Thus, we can understand that the LCM of 340,213,781,357 is 5576340.
