Given numbers are 248,781,239,434
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 248,781,239,434 is 324040024.
Find LCM of 248,781,239,434 with Prime Factorization
| 2 | 248, 781, 239, 434 |
| 31 | 124, 781, 239, 217 |
| 4, 781, 239, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 31 x 4 x 781 x 239 x 7 = 324040024
Therefore, the lowest common multiple of 248,781,239,434 is 324040024.
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.
248 x 781 x 239 x 434 = 20090481488
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.
248 : 1, 2, 4, 8, 31, 62, 124, 248
781 : 1, 11, 71, 781
239 : 1, 239
434 : 1, 2, 7, 14, 31, 62, 217, 434
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 248,781,239,434, is 1.
Now, the common factors can be found like this.
248:2x 2x 2x 31
781:11x 71
239:239
434:2x 7x 31
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 31 = 62
Therefore, the value for common factors is 62.
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 = 20090481488/(1x62)
LCM = 20090481488/62
LCM = 324040024
Thus, we can understand that the LCM of 248,781,239,434 is 324040024.
