Given numbers are 639,589,830,876
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 639,589,830,876 is 45608637780.
Find LCM of 639,589,830,876 with Prime Factorization
| 2 | 639, 589, 830, 876 |
| 3 | 639, 589, 415, 438 |
| 213, 589, 415, 146 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 213 x 589 x 415 x 146 = 45608637780
Therefore, the lowest common multiple of 639,589,830,876 is 45608637780.
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.
639 x 589 x 830 x 876 = 273651826680
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.
639 : 1, 3, 9, 71, 213, 639
589 : 1, 19, 31, 589
830 : 1, 2, 5, 10, 83, 166, 415, 830
876 : 1, 2, 3, 4, 6, 12, 73, 146, 219, 292, 438, 876
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 639,589,830,876, is 1.
Now, the common factors can be found like this.
639:3x 3x 71
589:19x 31
830:2x 5x 83
876:2x 2x 3x 73
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3 = 6
Therefore, the value for common factors is 6.
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 = 273651826680/(1x6)
LCM = 273651826680/6
LCM = 45608637780
Thus, we can understand that the LCM of 639,589,830,876 is 45608637780.
