Given numbers are 802,281,401,378,511
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 802,281,401,378,511 is 3109319514.
Find LCM of 802,281,401,378,511 with Prime Factorization
| 2 | 802, 281, 401, 378, 511 |
| 7 | 401, 281, 401, 189, 511 |
| 401 | 401, 281, 401, 27, 73 |
| 1, 281, 1, 27, 73 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 401 x 1 x 281 x 1 x 27 x 73 = 3109319514
Therefore, the lowest common multiple of 802,281,401,378,511 is 3109319514.
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.
802 x 281 x 401 x 378 x 511 = 17455719751596
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.
802 : 1, 2, 401, 802
281 : 1, 281
401 : 1, 401
378 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 27, 42, 54, 63, 126, 189, 378
511 : 1, 7, 73, 511
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 802,281,401,378,511, is 1.
Now, the common factors can be found like this.
802:2x 401
281:281
401:401
378:2x 3x 3x 3x 7
511:7x 73
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 7x 401 = 5614
Therefore, the value for common factors is 5614.
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 = 17455719751596/(1x5614)
LCM = 17455719751596/5614
LCM = 3109319514
Thus, we can understand that the LCM of 802,281,401,378,511 is 3109319514.
