Find LCM of 341,130,319,120,780 with Prime Factorization
| 2 | 341, 130, 319, 120, 780 |
| 2 | 341, 65, 319, 60, 390 |
| 3 | 341, 65, 319, 30, 195 |
| 5 | 341, 65, 319, 10, 65 |
| 11 | 341, 13, 319, 2, 13 |
| 13 | 31, 13, 29, 2, 13 |
| 31, 1, 29, 2, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 11 x 13 x 31 x 1 x 29 x 2 x 1 = 15426840
Therefore, the lowest common multiple of 341,130,319,120,780 is 15426840.
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.
341 x 130 x 319 x 120 x 780 = 1323622872000
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.
341 : 1, 11, 31, 341
130 : 1, 2, 5, 10, 13, 26, 65, 130
319 : 1, 11, 29, 319
120 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, 120
780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 341,130,319,120,780, is 1.
Now, the common factors can be found like this.
341:11x 31
130:2x 5x 13
319:11x 29
120:2x 2x 2x 3x 5
780:2x 2x 3x 5x 13
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 5x 5x 11x 13 = 85800
Therefore, the value for common factors is 85800.
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 = 1323622872000/(1x85800)
LCM = 1323622872000/85800
LCM = 15426840
Thus, we can understand that the LCM of 341,130,319,120,780 is 15426840.
