Given numbers are 652,851,639,891
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 652,851,639,891 is 35100492372.
Find LCM of 652,851,639,891 with Prime Factorization
| 3 | 652, 851, 639, 891 |
| 3 | 652, 851, 213, 297 |
| 652, 851, 71, 99 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 652 x 851 x 71 x 99 = 35100492372
Therefore, the lowest common multiple of 652,851,639,891 is 35100492372.
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.
652 x 851 x 639 x 891 = 315904431348
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.
652 : 1, 2, 4, 163, 326, 652
851 : 1, 23, 37, 851
639 : 1, 3, 9, 71, 213, 639
891 : 1, 3, 9, 11, 27, 33, 81, 99, 297, 891
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 652,851,639,891, is 1.
Now, the common factors can be found like this.
652:2x 2x 163
851:23x 37
639:3x 3x 71
891:3x 3x 3x 3x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3 = 9
Therefore, the value for common factors is 9.
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 = 315904431348/(1x9)
LCM = 315904431348/9
LCM = 35100492372
Thus, we can understand that the LCM of 652,851,639,891 is 35100492372.
