Given numbers are 257,897,469,623,755
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 257,897,469,623,755 is 7264995796695.
Find LCM of 257,897,469,623,755 with Prime Factorization
| 7 | 257, 897, 469, 623, 755 |
| 257, 897, 67, 89, 755 |
Multiply the prime numbers at the bottom and the left side.
7 x 257 x 897 x 67 x 89 x 755 = 7264995796695
Therefore, the lowest common multiple of 257,897,469,623,755 is 7264995796695.
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.
257 x 897 x 469 x 623 x 755 = 50854970576865
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.
257 : 1, 257
897 : 1, 3, 13, 23, 39, 69, 299, 897
469 : 1, 7, 67, 469
623 : 1, 7, 89, 623
755 : 1, 5, 151, 755
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 257,897,469,623,755, is 1.
Now, the common factors can be found like this.
257:257
897:3x 13x 23
469:7x 67
623:7x 89
755:5x 151
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
7 = 7
Therefore, the value for common factors is 7.
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 = 50854970576865/(1x7)
LCM = 50854970576865/7
LCM = 7264995796695
Thus, we can understand that the LCM of 257,897,469,623,755 is 7264995796695.
