Given numbers are 512,391,676,245,174
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 512,391,676,245,174 is 721138629120.
Find LCM of 512,391,676,245,174 with Prime Factorization
| 2 | 512, 391, 676, 245, 174 |
| 2 | 256, 391, 338, 245, 87 |
| 128, 391, 169, 245, 87 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 128 x 391 x 169 x 245 x 87 = 721138629120
Therefore, the lowest common multiple of 512,391,676,245,174 is 721138629120.
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.
512 x 391 x 676 x 245 x 174 = 5769109032960
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.
512 : 1, 2, 4, 8, 16, 32, 64, 128, 256, 512
391 : 1, 17, 23, 391
676 : 1, 2, 4, 13, 26, 52, 169, 338, 676
245 : 1, 5, 7, 35, 49, 245
174 : 1, 2, 3, 6, 29, 58, 87, 174
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 512,391,676,245,174, is 1.
Now, the common factors can be found like this.
512:2x 2x 2x 2x 2x 2x 2x 2x 2
391:17x 23
676:2x 2x 13x 13
245:5x 7x 7
174:2x 3x 29
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 2 = 8
Therefore, the value for common factors is 8.
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 = 5769109032960/(1x8)
LCM = 5769109032960/8
LCM = 721138629120
Thus, we can understand that the LCM of 512,391,676,245,174 is 721138629120.
