Given numbers are 800,782,643,854,782
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 800,782,643,854,782 is 85882680800.
Find LCM of 800,782,643,854,782 with Prime Factorization
2 | 800, 782, 643, 854, 782 |
17 | 400, 391, 643, 427, 391 |
23 | 400, 23, 643, 427, 23 |
400, 1, 643, 427, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 17 x 23 x 400 x 1 x 643 x 427 x 1 = 85882680800
Therefore, the lowest common multiple of 800,782,643,854,782 is 85882680800.
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.
800 x 782 x 643 x 854 x 782 = 268641025542400
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.
800 : 1, 2, 4, 5, 8, 10, 16, 20, 25, 32, 40, 50, 80, 100, 160, 200, 400, 800
782 : 1, 2, 17, 23, 34, 46, 391, 782
643 : 1, 643
854 : 1, 2, 7, 14, 61, 122, 427, 854
782 : 1, 2, 17, 23, 34, 46, 391, 782
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 800,782,643,854,782, is 1.
Now, the common factors can be found like this.
800:2x 2x 2x 2x 2x 5x 5
782:2x 17x 23
643:643
854:2x 7x 61
782:2x 17x 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 17x 23 = 3128
Therefore, the value for common factors is 3128.
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 = 268641025542400/(1x3128)
LCM = 268641025542400/3128
LCM = 85882680800
Thus, we can understand that the LCM of 800,782,643,854,782 is 85882680800.
