Given numbers are 476,289,782,621
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 476,289,782,621 is 5025132.
Find LCM of 476,289,782,621 with Prime Factorization
| 2 | 476, 289, 782, 621 |
| 17 | 238, 289, 391, 621 |
| 23 | 14, 17, 23, 621 |
| 14, 17, 1, 27 |
Multiply the prime numbers at the bottom and the left side.
2 x 17 x 23 x 14 x 17 x 1 x 27 = 5025132
Therefore, the lowest common multiple of 476,289,782,621 is 5025132.
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.
476 x 289 x 782 x 621 = 66804104808
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.
476 : 1, 2, 4, 7, 14, 17, 28, 34, 68, 119, 238, 476
289 : 1, 17, 289
782 : 1, 2, 17, 23, 34, 46, 391, 782
621 : 1, 3, 9, 23, 27, 69, 207, 621
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 476,289,782,621, is 1.
Now, the common factors can be found like this.
476:2x 2x 7x 17
289:17x 17
782:2x 17x 23
621:3x 3x 3x 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 17x 17x 23 = 13294
Therefore, the value for common factors is 13294.
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 = 66804104808/(1x13294)
LCM = 66804104808/13294
LCM = 5025132
Thus, we can understand that the LCM of 476,289,782,621 is 5025132.
