Given numbers are 892,804,855,931
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 892,804,855,931 is 2503812780.
Find LCM of 892,804,855,931 with Prime Factorization
| 2 | 892, 804, 855, 931 |
| 2 | 446, 402, 855, 931 |
| 3 | 223, 201, 855, 931 |
| 19 | 223, 67, 285, 931 |
| 223, 67, 15, 49 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 19 x 223 x 67 x 15 x 49 = 2503812780
Therefore, the lowest common multiple of 892,804,855,931 is 2503812780.
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.
892 x 804 x 855 x 931 = 570869313840
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.
892 : 1, 2, 4, 223, 446, 892
804 : 1, 2, 3, 4, 6, 12, 67, 134, 201, 268, 402, 804
855 : 1, 3, 5, 9, 15, 19, 45, 57, 95, 171, 285, 855
931 : 1, 7, 19, 49, 133, 931
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 892,804,855,931, is 1.
Now, the common factors can be found like this.
892:2x 2x 223
804:2x 2x 3x 67
855:3x 3x 5x 19
931:7x 7x 19
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 19 = 228
Therefore, the value for common factors is 228.
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 = 570869313840/(1x228)
LCM = 570869313840/228
LCM = 2503812780
Thus, we can understand that the LCM of 892,804,855,931 is 2503812780.
