Find LCM of 342,721,855,967,309 with Prime Factorization
| 3 | 342, 721, 855, 967, 309 |
| 3 | 114, 721, 285, 967, 103 |
| 19 | 38, 721, 95, 967, 103 |
| 103 | 2, 721, 5, 967, 103 |
| 2, 7, 5, 967, 1 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 19 x 103 x 2 x 7 x 5 x 967 x 1 = 1192223970
Therefore, the lowest common multiple of 342,721,855,967,309 is 1192223970.
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 721 x 855 x 967 x 309 = 62995922350830
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
721 : 1, 7, 103, 721
855 : 1, 3, 5, 9, 15, 19, 45, 57, 95, 171, 285, 855
967 : 1, 967
309 : 1, 3, 103, 309
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 342,721,855,967,309, is 1.
Now, the common factors can be found like this.
342:2x 3x 3x 19
721:7x 103
855:3x 3x 5x 19
967:967
309:3x 103
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 3x 19x 103 = 52839
Therefore, the value for common factors is 52839.
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 = 62995922350830/(1x52839)
LCM = 62995922350830/52839
LCM = 1192223970
Thus, we can understand that the LCM of 342,721,855,967,309 is 1192223970.
