Given numbers are 278,808,478,239
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 278,808,478,239 is 26842568.
Find LCM of 278,808,478,239 with Prime Factorization
| 2 | 278, 808, 478, 239 |
| 239 | 139, 404, 239, 239 |
| 139, 404, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 239 x 139 x 404 x 1 x 1 = 26842568
Therefore, the lowest common multiple of 278,808,478,239 is 26842568.
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.
278 x 808 x 478 x 239 = 25661495008
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.
278 : 1, 2, 139, 278
808 : 1, 2, 4, 8, 101, 202, 404, 808
478 : 1, 2, 239, 478
239 : 1, 239
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 278,808,478,239, is 1.
Now, the common factors can be found like this.
278:2x 139
808:2x 2x 2x 101
478:2x 239
239:239
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 239 = 956
Therefore, the value for common factors is 956.
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 = 25661495008/(1x956)
LCM = 25661495008/956
LCM = 26842568
Thus, we can understand that the LCM of 278,808,478,239 is 26842568.
