Given numbers are 655,830,332,538
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 655,830,332,538 is 58496740.
Find LCM of 655,830,332,538 with Prime Factorization
| 2 | 655, 830, 332, 538 |
| 5 | 655, 415, 166, 269 |
| 83 | 131, 83, 166, 269 |
| 131, 1, 2, 269 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 83 x 131 x 1 x 2 x 269 = 58496740
Therefore, the lowest common multiple of 655,830,332,538 is 58496740.
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.
655 x 830 x 332 x 538 = 97104588400
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.
655 : 1, 5, 131, 655
830 : 1, 2, 5, 10, 83, 166, 415, 830
332 : 1, 2, 4, 83, 166, 332
538 : 1, 2, 269, 538
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 655,830,332,538, is 1.
Now, the common factors can be found like this.
655:5x 131
830:2x 5x 83
332:2x 2x 83
538:2x 269
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 5x 83 = 1660
Therefore, the value for common factors is 1660.
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 = 97104588400/(1x1660)
LCM = 97104588400/1660
LCM = 58496740
Thus, we can understand that the LCM of 655,830,332,538 is 58496740.
