Given numbers are 447,503,808,515,721
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 447,503,808,515,721 is 654925858440.
Find LCM of 447,503,808,515,721 with Prime Factorization
103 | 447, 503, 808, 515, 721 |
447, 503, 808, 5, 7 |
Multiply the prime numbers at the bottom and the left side.
103 x 447 x 503 x 808 x 5 x 7 = 654925858440
Therefore, the lowest common multiple of 447,503,808,515,721 is 654925858440.
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.
447 x 503 x 808 x 515 x 721 = 67457363419320
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.
447 : 1, 3, 149, 447
503 : 1, 503
808 : 1, 2, 4, 8, 101, 202, 404, 808
515 : 1, 5, 103, 515
721 : 1, 7, 103, 721
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 447,503,808,515,721, is 1.
Now, the common factors can be found like this.
447:3x 149
503:503
808:2x 2x 2x 101
515:5x 103
721:7x 103
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
103 = 103
Therefore, the value for common factors is 103.
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 = 67457363419320/(1x103)
LCM = 67457363419320/103
LCM = 654925858440
Thus, we can understand that the LCM of 447,503,808,515,721 is 654925858440.
