Find LCM of 405,977,270,812 with Prime Factorization
2 | 405, 977, 270, 812 |
3 | 405, 977, 135, 406 |
3 | 45, 977, 135, 406 |
3 | 15, 977, 45, 406 |
5 | 5, 977, 15, 406 |
1, 977, 3, 406 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 3 x 5 x 1 x 977 x 3 x 406 = 321296220
Therefore, the lowest common multiple of 405,977,270,812 is 321296220.
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.
405 x 977 x 270 x 812 = 86749979400
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.
405 : 1, 3, 5, 9, 15, 27, 45, 81, 135, 405
977 : 1, 977
270 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 27, 30, 45, 54, 90, 135, 270
812 : 1, 2, 4, 7, 14, 28, 29, 58, 116, 203, 406, 812
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 405,977,270,812, is 1.
Now, the common factors can be found like this.
405:3x 3x 3x 3x 5
977:977
270:2x 3x 3x 3x 5
812:2x 2x 7x 29
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 3x 3x 5 = 270
Therefore, the value for common factors is 270.
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 = 86749979400/(1x270)
LCM = 86749979400/270
LCM = 321296220
Thus, we can understand that the LCM of 405,977,270,812 is 321296220.
