Given numbers are 405,697,440,878
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 405,697,440,878 is 10905234120.
Find LCM of 405,697,440,878 with Prime Factorization
2 | 405, 697, 440, 878 |
5 | 405, 697, 220, 439 |
81, 697, 44, 439 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 81 x 697 x 44 x 439 = 10905234120
Therefore, the lowest common multiple of 405,697,440,878 is 10905234120.
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 697 x 440 x 878 = 109052341200
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
697 : 1, 17, 41, 697
440 : 1, 2, 4, 5, 8, 10, 11, 20, 22, 40, 44, 55, 88, 110, 220, 440
878 : 1, 2, 439, 878
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 405,697,440,878, is 1.
Now, the common factors can be found like this.
405:3x 3x 3x 3x 5
697:17x 41
440:2x 2x 2x 5x 11
878:2x 439
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5 = 10
Therefore, the value for common factors is 10.
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 = 109052341200/(1x10)
LCM = 109052341200/10
LCM = 10905234120
Thus, we can understand that the LCM of 405,697,440,878 is 10905234120.
