Given numbers are 581,651,646,338,851
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 581,651,646,338,851 is 5020047929442.
Find LCM of 581,651,646,338,851 with Prime Factorization
| 2 | 581, 651, 646, 338, 851 |
| 7 | 581, 651, 323, 169, 851 |
| 83, 93, 323, 169, 851 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 83 x 93 x 323 x 169 x 851 = 5020047929442
Therefore, the lowest common multiple of 581,651,646,338,851 is 5020047929442.
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.
581 x 651 x 646 x 338 x 851 = 70280671012188
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.
581 : 1, 7, 83, 581
651 : 1, 3, 7, 21, 31, 93, 217, 651
646 : 1, 2, 17, 19, 34, 38, 323, 646
338 : 1, 2, 13, 26, 169, 338
851 : 1, 23, 37, 851
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 581,651,646,338,851, is 1.
Now, the common factors can be found like this.
581:7x 83
651:3x 7x 31
646:2x 17x 19
338:2x 13x 13
851:23x 37
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 7 = 14
Therefore, the value for common factors is 14.
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 = 70280671012188/(1x14)
LCM = 70280671012188/14
LCM = 5020047929442
Thus, we can understand that the LCM of 581,651,646,338,851 is 5020047929442.
