Given numbers are 655,842,670,429,871
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 655,842,670,429,871 is 15852051930.
Find LCM of 655,842,670,429,871 with Prime Factorization
| 2 | 655, 842, 670, 429, 871 |
| 5 | 655, 421, 335, 429, 871 |
| 13 | 131, 421, 67, 429, 871 |
| 67 | 131, 421, 67, 33, 67 |
| 131, 421, 1, 33, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 13 x 67 x 131 x 421 x 1 x 33 x 1 = 15852051930
Therefore, the lowest common multiple of 655,842,670,429,871 is 15852051930.
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 842 x 670 x 429 x 871 = 138071372310300
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
842 : 1, 2, 421, 842
670 : 1, 2, 5, 10, 67, 134, 335, 670
429 : 1, 3, 11, 13, 33, 39, 143, 429
871 : 1, 13, 67, 871
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 655,842,670,429,871, is 1.
Now, the common factors can be found like this.
655:5x 131
842:2x 421
670:2x 5x 67
429:3x 11x 13
871:13x 67
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 13x 67 = 8710
Therefore, the value for common factors is 8710.
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 = 138071372310300/(1x8710)
LCM = 138071372310300/8710
LCM = 15852051930
Thus, we can understand that the LCM of 655,842,670,429,871 is 15852051930.
