Given numbers are 486,861,574,987
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 486,861,574,987 is 6555654.
Find LCM of 486,861,574,987 with Prime Factorization
2 | 486, 861, 574, 987 |
3 | 243, 861, 287, 987 |
7 | 81, 287, 287, 329 |
41 | 81, 41, 41, 47 |
81, 1, 1, 47 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 41 x 81 x 1 x 1 x 47 = 6555654
Therefore, the lowest common multiple of 486,861,574,987 is 6555654.
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.
486 x 861 x 574 x 987 = 237065559948
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.
486 : 1, 2, 3, 6, 9, 18, 27, 54, 81, 162, 243, 486
861 : 1, 3, 7, 21, 41, 123, 287, 861
574 : 1, 2, 7, 14, 41, 82, 287, 574
987 : 1, 3, 7, 21, 47, 141, 329, 987
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 486,861,574,987, is 1.
Now, the common factors can be found like this.
486:2x 3x 3x 3x 3x 3
861:3x 7x 41
574:2x 7x 41
987:3x 7x 47
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 7x 7x 41 = 36162
Therefore, the value for common factors is 36162.
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 = 237065559948/(1x36162)
LCM = 237065559948/36162
LCM = 6555654
Thus, we can understand that the LCM of 486,861,574,987 is 6555654.
