Given numbers are 685,198,331,820,695
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 685,198,331,820,695 is 511696454940.
Find LCM of 685,198,331,820,695 with Prime Factorization
| 2 | 685, 198, 331, 820, 695 |
| 5 | 685, 99, 331, 410, 695 |
| 137, 99, 331, 82, 139 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 137 x 99 x 331 x 82 x 139 = 511696454940
Therefore, the lowest common multiple of 685,198,331,820,695 is 511696454940.
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.
685 x 198 x 331 x 820 x 695 = 25584822747000
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.
685 : 1, 5, 137, 685
198 : 1, 2, 3, 6, 9, 11, 18, 22, 33, 66, 99, 198
331 : 1, 331
820 : 1, 2, 4, 5, 10, 20, 41, 82, 164, 205, 410, 820
695 : 1, 5, 139, 695
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 685,198,331,820,695, is 1.
Now, the common factors can be found like this.
685:5x 137
198:2x 3x 3x 11
331:331
820:2x 2x 5x 41
695:5x 139
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 5 = 50
Therefore, the value for common factors is 50.
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 = 25584822747000/(1x50)
LCM = 25584822747000/50
LCM = 511696454940
Thus, we can understand that the LCM of 685,198,331,820,695 is 511696454940.
