The LCM of 405,642,714,910 is 134078490.
Find LCM of 405,642,714,910 with Prime Factorization
2 | 405, 642, 714, 910 |
3 | 405, 321, 357, 455 |
5 | 135, 107, 119, 455 |
7 | 27, 107, 119, 91 |
27, 107, 17, 13 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 7 x 27 x 107 x 17 x 13 = 134078490
Therefore, the lowest common multiple of 405,642,714,910 is 134078490.
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 642 x 714 x 910 = 168938897400
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
642 : 1, 2, 3, 6, 107, 214, 321, 642
714 : 1, 2, 3, 6, 7, 14, 17, 21, 34, 42, 51, 102, 119, 238, 357, 714
910 : 1, 2, 5, 7, 10, 13, 14, 26, 35, 65, 70, 91, 130, 182, 455, 910
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 405,642,714,910, is 1.
Now, the common factors can be found like this.
405:3x 3x 3x 3x 5
642:2x 3x 107
714:2x 3x 7x 17
910:2x 5x 7x 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 3x 3x 5x 7 = 1260
Therefore, the value for common factors is 1260.
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 = 168938897400/(1x1260)
LCM = 168938897400/1260
LCM = 134078490
Thus, we can understand that the LCM of 405,642,714,910 is 134078490.
