Given numbers are 7,819,715,650
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 7,819,715,650 is 450450.
Find LCM of 7,819,715,650 with Prime Factorization
5 | 7, 819, 715, 650 |
7 | 7, 819, 143, 130 |
13 | 1, 117, 143, 130 |
1, 9, 11, 10 |
Multiply the prime numbers at the bottom and the left side.
5 x 7 x 13 x 1 x 9 x 11 x 10 = 450450
Therefore, the lowest common multiple of 7,819,715,650 is 450450.
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.
7 x 819 x 715 x 650 = 2664411750
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.
7 : 1, 7
819 : 1, 3, 7, 9, 13, 21, 39, 63, 91, 117, 273, 819
715 : 1, 5, 11, 13, 55, 65, 143, 715
650 : 1, 2, 5, 10, 13, 25, 26, 50, 65, 130, 325, 650
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 7,819,715,650, is 1.
Now, the common factors can be found like this.
7:7
819:3x 3x 7x 13
715:5x 11x 13
650:2x 5x 5x 13
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 13x 13 = 5915
Therefore, the value for common factors is 5915.
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 = 2664411750/(1x5915)
LCM = 2664411750/5915
LCM = 450450
Thus, we can understand that the LCM of 7,819,715,650 is 450450.
