Given numbers are 405,931,153,693,695
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 405,931,153,693,695 is 9800790615.
Find LCM of 405,931,153,693,695 with Prime Factorization
| 3 | 405, 931, 153, 693, 695 |
| 3 | 135, 931, 51, 231, 695 |
| 5 | 45, 931, 17, 77, 695 |
| 7 | 9, 931, 17, 77, 139 |
| 9, 133, 17, 11, 139 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 5 x 7 x 9 x 133 x 17 x 11 x 139 = 9800790615
Therefore, the lowest common multiple of 405,931,153,693,695 is 9800790615.
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 931 x 153 x 693 x 695 = 27785241393525
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
931 : 1, 7, 19, 49, 133, 931
153 : 1, 3, 9, 17, 51, 153
693 : 1, 3, 7, 9, 11, 21, 33, 63, 77, 99, 231, 693
695 : 1, 5, 139, 695
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 405,931,153,693,695, is 1.
Now, the common factors can be found like this.
405:3x 3x 3x 3x 5
931:7x 7x 19
153:3x 3x 17
693:3x 3x 7x 11
695:5x 139
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 3x 5x 7 = 2835
Therefore, the value for common factors is 2835.
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 = 27785241393525/(1x2835)
LCM = 27785241393525/2835
LCM = 9800790615
Thus, we can understand that the LCM of 405,931,153,693,695 is 9800790615.
