Given numbers are 239,831,221,478,688
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 239,831,221,478,688 is 30198101232.
Find LCM of 239,831,221,478,688 with Prime Factorization
| 2 | 239, 831, 221, 478, 688 |
| 239 | 239, 831, 221, 239, 344 |
| 1, 831, 221, 1, 344 |
Multiply the prime numbers at the bottom and the left side.
2 x 239 x 1 x 831 x 221 x 1 x 344 = 30198101232
Therefore, the lowest common multiple of 239,831,221,478,688 is 30198101232.
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.
239 x 831 x 221 x 478 x 688 = 14434692388896
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.
239 : 1, 239
831 : 1, 3, 277, 831
221 : 1, 13, 17, 221
478 : 1, 2, 239, 478
688 : 1, 2, 4, 8, 16, 43, 86, 172, 344, 688
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 239,831,221,478,688, is 1.
Now, the common factors can be found like this.
239:239
831:3x 277
221:13x 17
478:2x 239
688:2x 2x 2x 2x 43
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 239 = 478
Therefore, the value for common factors is 478.
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 = 14434692388896/(1x478)
LCM = 14434692388896/478
LCM = 30198101232
Thus, we can understand that the LCM of 239,831,221,478,688 is 30198101232.
