Given numbers are 845,655,689,143
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 845,655,689,143 is 64535185.
Find LCM of 845,655,689,143 with Prime Factorization
5 | 845, 655, 689, 143 |
13 | 169, 131, 689, 143 |
13, 131, 53, 11 |
Multiply the prime numbers at the bottom and the left side.
5 x 13 x 13 x 131 x 53 x 11 = 64535185
Therefore, the lowest common multiple of 845,655,689,143 is 64535185.
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.
845 x 655 x 689 x 143 = 54532231325
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.
845 : 1, 5, 13, 65, 169, 845
655 : 1, 5, 131, 655
689 : 1, 13, 53, 689
143 : 1, 11, 13, 143
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 845,655,689,143, is 1.
Now, the common factors can be found like this.
845:5x 13x 13
655:5x 131
689:13x 53
143:11x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5x 13x 13 = 845
Therefore, the value for common factors is 845.
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 = 54532231325/(1x845)
LCM = 54532231325/845
LCM = 64535185
Thus, we can understand that the LCM of 845,655,689,143 is 64535185.
