Given numbers are 526,683,638,781
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 526,683,638,781 is 8136834442.
Find LCM of 526,683,638,781 with Prime Factorization
| 2 | 526, 683, 638, 781 |
| 11 | 263, 683, 319, 781 |
| 263, 683, 29, 71 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 263 x 683 x 29 x 71 = 8136834442
Therefore, the lowest common multiple of 526,683,638,781 is 8136834442.
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.
526 x 683 x 638 x 781 = 179010357724
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.
526 : 1, 2, 263, 526
683 : 1, 683
638 : 1, 2, 11, 22, 29, 58, 319, 638
781 : 1, 11, 71, 781
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 526,683,638,781, is 1.
Now, the common factors can be found like this.
526:2x 263
683:683
638:2x 11x 29
781:11x 71
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 11 = 22
Therefore, the value for common factors is 22.
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 = 179010357724/(1x22)
LCM = 179010357724/22
LCM = 8136834442
Thus, we can understand that the LCM of 526,683,638,781 is 8136834442.
