Given numbers are 257,669,648,579
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 257,669,648,579 is 7167542904.
Find LCM of 257,669,648,579 with Prime Factorization
| 3 | 257, 669, 648, 579 |
| 257, 223, 216, 193 |
Multiply the prime numbers at the bottom and the left side.
3 x 257 x 223 x 216 x 193 = 7167542904
Therefore, the lowest common multiple of 257,669,648,579 is 7167542904.
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 669 x 648 x 579 = 64507886136
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
669 : 1, 3, 223, 669
648 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 81, 108, 162, 216, 324, 648
579 : 1, 3, 193, 579
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 257,669,648,579, is 1.
Now, the common factors can be found like this.
257:257
669:3x 223
648:2x 2x 2x 3x 3x 3x 3
579:3x 193
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 = 64507886136/(1x9)
LCM = 64507886136/9
LCM = 7167542904
Thus, we can understand that the LCM of 257,669,648,579 is 7167542904.
