Find LCM of 342,945,634,518,540 with Prime Factorization
| 2 | 342, 945, 634, 518, 540 |
| 3 | 171, 945, 317, 259, 270 |
| 3 | 57, 315, 317, 259, 90 |
| 3 | 19, 105, 317, 259, 30 |
| 5 | 19, 35, 317, 259, 10 |
| 7 | 19, 7, 317, 259, 2 |
| 19, 1, 317, 37, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 3 x 5 x 7 x 19 x 1 x 317 x 37 x 2 = 842376780
Therefore, the lowest common multiple of 342,945,634,518,540 is 842376780.
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.
342 x 945 x 634 x 518 x 540 = 57315316111200
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.
342 : 1, 2, 3, 6, 9, 18, 19, 38, 57, 114, 171, 342
945 : 1, 3, 5, 7, 9, 15, 21, 27, 35, 45, 63, 105, 135, 189, 315, 945
634 : 1, 2, 317, 634
518 : 1, 2, 7, 14, 37, 74, 259, 518
540 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 27, 30, 36, 45, 54, 60, 90, 108, 135, 180, 270, 540
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 342,945,634,518,540, is 1.
Now, the common factors can be found like this.
342:2x 3x 3x 19
945:3x 3x 3x 5x 7
634:2x 317
518:2x 7x 37
540:2x 2x 3x 3x 3x 5
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 3x 3x 3x 3x 5x 7 = 68040
Therefore, the value for common factors is 68040.
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 = 57315316111200/(1x68040)
LCM = 57315316111200/68040
LCM = 842376780
Thus, we can understand that the LCM of 342,945,634,518,540 is 842376780.
