Given numbers are 808,243,421,714,994
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 808,243,421,714,994 is 698401301976.
Find LCM of 808,243,421,714,994 with Prime Factorization
| 2 | 808, 243, 421, 714, 994 |
| 3 | 404, 243, 421, 357, 497 |
| 7 | 404, 81, 421, 119, 497 |
| 404, 81, 421, 17, 71 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 404 x 81 x 421 x 17 x 71 = 698401301976
Therefore, the lowest common multiple of 808,243,421,714,994 is 698401301976.
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.
808 x 243 x 421 x 714 x 994 = 58665709365984
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.
808 : 1, 2, 4, 8, 101, 202, 404, 808
243 : 1, 3, 9, 27, 81, 243
421 : 1, 421
714 : 1, 2, 3, 6, 7, 14, 17, 21, 34, 42, 51, 102, 119, 238, 357, 714
994 : 1, 2, 7, 14, 71, 142, 497, 994
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 808,243,421,714,994, is 1.
Now, the common factors can be found like this.
808:2x 2x 2x 101
243:3x 3x 3x 3x 3
421:421
714:2x 3x 7x 17
994:2x 7x 71
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 3x 7 = 84
Therefore, the value for common factors is 84.
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 = 58665709365984/(1x84)
LCM = 58665709365984/84
LCM = 698401301976
Thus, we can understand that the LCM of 808,243,421,714,994 is 698401301976.
