Given numbers are 816,578,986,785
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 816,578,986,785 is 315796080.
Find LCM of 816,578,986,785 with Prime Factorization
2 | 816, 578, 986, 785 |
17 | 408, 289, 493, 785 |
24, 17, 29, 785 |
Multiply the prime numbers at the bottom and the left side.
2 x 17 x 24 x 17 x 29 x 785 = 315796080
Therefore, the lowest common multiple of 816,578,986,785 is 315796080.
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.
816 x 578 x 986 x 785 = 365060268480
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.
816 : 1, 2, 3, 4, 6, 8, 12, 16, 17, 24, 34, 48, 51, 68, 102, 136, 204, 272, 408, 816
578 : 1, 2, 17, 34, 289, 578
986 : 1, 2, 17, 29, 34, 58, 493, 986
785 : 1, 5, 157, 785
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 816,578,986,785, is 1.
Now, the common factors can be found like this.
816:2x 2x 2x 2x 3x 17
578:2x 17x 17
986:2x 17x 29
785:5x 157
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 17x 17 = 1156
Therefore, the value for common factors is 1156.
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 = 365060268480/(1x1156)
LCM = 365060268480/1156
LCM = 315796080
Thus, we can understand that the LCM of 816,578,986,785 is 315796080.
