Given numbers are 782,890,400,862,460
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 782,890,400,862,460 is 5999347600.
Find LCM of 782,890,400,862,460 with Prime Factorization
2 | 782, 890, 400, 862, 460 |
2 | 391, 445, 200, 431, 230 |
5 | 391, 445, 100, 431, 115 |
23 | 391, 89, 20, 431, 23 |
17, 89, 20, 431, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 23 x 17 x 89 x 20 x 431 x 1 = 5999347600
Therefore, the lowest common multiple of 782,890,400,862,460 is 5999347600.
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.
782 x 890 x 400 x 862 x 460 = 110387995840000
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.
782 : 1, 2, 17, 23, 34, 46, 391, 782
890 : 1, 2, 5, 10, 89, 178, 445, 890
400 : 1, 2, 4, 5, 8, 10, 16, 20, 25, 40, 50, 80, 100, 200, 400
862 : 1, 2, 431, 862
460 : 1, 2, 4, 5, 10, 20, 23, 46, 92, 115, 230, 460
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 782,890,400,862,460, is 2.
Now, the common factors can be found like this.
782:2x 17x 23
890:2x 5x 89
400:2x 2x 2x 2x 5x 5
862:2x 431
460:2x 2x 5x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 2x 2x 5x 5x 23 = 9200
Therefore, the value for common factors is 9200.
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 = 110387995840000/(2x9200)
LCM = 110387995840000/18400
LCM = 5999347600
Thus, we can understand that the LCM of 782,890,400,862,460 is 5999347600.
