Given numbers are 480,845,689,819
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 480,845,689,819 is 90286560.
Find LCM of 480,845,689,819 with Prime Factorization
3 | 480, 845, 689, 819 |
5 | 160, 845, 689, 273 |
13 | 32, 169, 689, 273 |
32, 13, 53, 21 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 13 x 32 x 13 x 53 x 21 = 90286560
Therefore, the lowest common multiple of 480,845,689,819 is 90286560.
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.
480 x 845 x 689 x 819 = 228876429600
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.
480 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 32, 40, 48, 60, 80, 96, 120, 160, 240, 480
845 : 1, 5, 13, 65, 169, 845
689 : 1, 13, 53, 689
819 : 1, 3, 7, 9, 13, 21, 39, 63, 91, 117, 273, 819
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 480,845,689,819, is 1.
Now, the common factors can be found like this.
480:2x 2x 2x 2x 2x 3x 5
845:5x 13x 13
689:13x 53
819:3x 3x 7x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 5x 13x 13 = 2535
Therefore, the value for common factors is 2535.
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 = 228876429600/(1x2535)
LCM = 228876429600/2535
LCM = 90286560
Thus, we can understand that the LCM of 480,845,689,819 is 90286560.
