Given numbers are 639,168,431,377,489
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 639,168,431,377,489 is 947752873704.
Find LCM of 639,168,431,377,489 with Prime Factorization
3 | 639, 168, 431, 377, 489 |
213, 56, 431, 377, 163 |
Multiply the prime numbers at the bottom and the left side.
3 x 213 x 56 x 431 x 377 x 163 = 947752873704
Therefore, the lowest common multiple of 639,168,431,377,489 is 947752873704.
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 168 x 431 x 377 x 489 = 8529775863336
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
168 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 21, 24, 28, 42, 56, 84, 168
431 : 1, 431
377 : 1, 13, 29, 377
489 : 1, 3, 163, 489
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 639,168,431,377,489, is 1.
Now, the common factors can be found like this.
639:3x 3x 71
168:2x 2x 2x 3x 7
431:431
377:13x 29
489:3x 163
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3 = 9
Therefore, the value for common factors is 9.
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 = 8529775863336/(1x9)
LCM = 8529775863336/9
LCM = 947752873704
Thus, we can understand that the LCM of 639,168,431,377,489 is 947752873704.
