Given numbers are 802,278,502,918,257
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 802,278,502,918,257 is 3300720107814.
Find LCM of 802,278,502,918,257 with Prime Factorization
| 2 | 802, 278, 502, 918, 257 |
| 401, 139, 251, 459, 257 |
Multiply the prime numbers at the bottom and the left side.
2 x 401 x 139 x 251 x 459 x 257 = 3300720107814
Therefore, the lowest common multiple of 802,278,502,918,257 is 3300720107814.
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 278 x 502 x 918 x 257 = 26405760862512
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
278 : 1, 2, 139, 278
502 : 1, 2, 251, 502
918 : 1, 2, 3, 6, 9, 17, 18, 27, 34, 51, 54, 102, 153, 306, 459, 918
257 : 1, 257
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 802,278,502,918,257, is 1.
Now, the common factors can be found like this.
802:2x 401
278:2x 139
502:2x 251
918:2x 3x 3x 3x 17
257:257
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 2 = 8
Therefore, the value for common factors is 8.
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 = 26405760862512/(1x8)
LCM = 26405760862512/8
LCM = 3300720107814
Thus, we can understand that the LCM of 802,278,502,918,257 is 3300720107814.
