Given numbers are 851,481,676,646
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 851,481,676,646 is 185814148.
Find LCM of 851,481,676,646 with Prime Factorization
| 2 | 851, 481, 676, 646 |
| 13 | 851, 481, 338, 323 |
| 37 | 851, 37, 26, 323 |
| 23, 1, 26, 323 |
Multiply the prime numbers at the bottom and the left side.
2 x 13 x 37 x 23 x 1 x 26 x 323 = 185814148
Therefore, the lowest common multiple of 851,481,676,646 is 185814148.
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.
851 x 481 x 676 x 646 = 178753210376
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.
851 : 1, 23, 37, 851
481 : 1, 13, 37, 481
676 : 1, 2, 4, 13, 26, 52, 169, 338, 676
646 : 1, 2, 17, 19, 34, 38, 323, 646
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 851,481,676,646, is 1.
Now, the common factors can be found like this.
851:23x 37
481:13x 37
676:2x 2x 13x 13
646:2x 17x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 13x 37 = 962
Therefore, the value for common factors is 962.
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 = 178753210376/(1x962)
LCM = 178753210376/962
LCM = 185814148
Thus, we can understand that the LCM of 851,481,676,646 is 185814148.
