Given numbers are 639,385,511,980,827
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 639,385,511,980,827 is 415860803820.
Find LCM of 639,385,511,980,827 with Prime Factorization
5 | 639, 385, 511, 980, 827 |
7 | 639, 77, 511, 196, 827 |
639, 11, 73, 28, 827 |
Multiply the prime numbers at the bottom and the left side.
5 x 7 x 639 x 11 x 73 x 28 x 827 = 415860803820
Therefore, the lowest common multiple of 639,385,511,980,827 is 415860803820.
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 385 x 511 x 980 x 827 = 101885896935900
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
385 : 1, 5, 7, 11, 35, 55, 77, 385
511 : 1, 7, 73, 511
980 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 49, 70, 98, 140, 196, 245, 490, 980
827 : 1, 827
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 639,385,511,980,827, is 1.
Now, the common factors can be found like this.
639:3x 3x 71
385:5x 7x 11
511:7x 73
980:2x 2x 5x 7x 7
827:827
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5x 7x 7 = 245
Therefore, the value for common factors is 245.
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 = 101885896935900/(1x245)
LCM = 101885896935900/245
LCM = 415860803820
Thus, we can understand that the LCM of 639,385,511,980,827 is 415860803820.
