Given numbers are 609,861,100,686,648
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 609,861,100,686,648 is 6606797400.
Find LCM of 609,861,100,686,648 with Prime Factorization
2 | 609, 861, 100, 686, 648 |
2 | 609, 861, 50, 343, 324 |
3 | 609, 861, 25, 343, 162 |
7 | 203, 287, 25, 343, 54 |
29, 41, 25, 49, 54 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 7 x 29 x 41 x 25 x 49 x 54 = 6606797400
Therefore, the lowest common multiple of 609,861,100,686,648 is 6606797400.
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.
609 x 861 x 100 x 686 x 648 = 23308781227200
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.
609 : 1, 3, 7, 21, 29, 87, 203, 609
861 : 1, 3, 7, 21, 41, 123, 287, 861
100 : 1, 2, 4, 5, 10, 20, 25, 50, 100
686 : 1, 2, 7, 14, 49, 98, 343, 686
648 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 81, 108, 162, 216, 324, 648
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 609,861,100,686,648, is 1.
Now, the common factors can be found like this.
609:3x 7x 29
861:3x 7x 41
100:2x 2x 5x 5
686:2x 7x 7x 7
648:2x 2x 2x 3x 3x 3x 3
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 2x 3x 3x 7x 7 = 3528
Therefore, the value for common factors is 3528.
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 = 23308781227200/(1x3528)
LCM = 23308781227200/3528
LCM = 6606797400
Thus, we can understand that the LCM of 609,861,100,686,648 is 6606797400.
