Given numbers are 647,575,713,805
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 647,575,713,805 is 80729425.
Find LCM of 647,575,713,805 with Prime Factorization
5 | 647, 575, 713, 805 |
23 | 647, 115, 713, 161 |
647, 5, 31, 7 |
Multiply the prime numbers at the bottom and the left side.
5 x 23 x 647 x 5 x 31 x 7 = 80729425
Therefore, the lowest common multiple of 647,575,713,805 is 80729425.
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.
647 x 575 x 713 x 805 = 213529329125
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.
647 : 1, 647
575 : 1, 5, 23, 25, 115, 575
713 : 1, 23, 31, 713
805 : 1, 5, 7, 23, 35, 115, 161, 805
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 647,575,713,805, is 1.
Now, the common factors can be found like this.
647:647
575:5x 5x 23
713:23x 31
805:5x 7x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5x 23x 23 = 2645
Therefore, the value for common factors is 2645.
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 = 213529329125/(1x2645)
LCM = 213529329125/2645
LCM = 80729425
Thus, we can understand that the LCM of 647,575,713,805 is 80729425.
