Given numbers are 630,809,365,855
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 630,809,365,855 is 706912290.
Find LCM of 630,809,365,855 with Prime Factorization
3 | 630, 809, 365, 855 |
3 | 210, 809, 365, 285 |
5 | 70, 809, 365, 95 |
14, 809, 73, 19 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 5 x 14 x 809 x 73 x 19 = 706912290
Therefore, the lowest common multiple of 630,809,365,855 is 706912290.
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.
630 x 809 x 365 x 855 = 159055265250
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.
630 : 1, 2, 3, 5, 6, 7, 9, 10, 14, 15, 18, 21, 30, 35, 42, 45, 63, 70, 90, 105, 126, 210, 315, 630
809 : 1, 809
365 : 1, 5, 73, 365
855 : 1, 3, 5, 9, 15, 19, 45, 57, 95, 171, 285, 855
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 630,809,365,855, is 1.
Now, the common factors can be found like this.
630:2x 3x 3x 5x 7
809:809
365:5x 73
855:3x 3x 5x 19
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 5x 5 = 225
Therefore, the value for common factors is 225.
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 = 159055265250/(1x225)
LCM = 159055265250/225
LCM = 706912290
Thus, we can understand that the LCM of 630,809,365,855 is 706912290.
