Given numbers are 309,869,395,521
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 309,869,395,521 is 699497205.
Find LCM of 309,869,395,521 with Prime Factorization
79 | 309, 869, 395, 521 |
309, 11, 5, 521 |
Multiply the prime numbers at the bottom and the left side.
79 x 309 x 11 x 5 x 521 = 699497205
Therefore, the lowest common multiple of 309,869,395,521 is 699497205.
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.
309 x 869 x 395 x 521 = 55260279195
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.
309 : 1, 3, 103, 309
869 : 1, 11, 79, 869
395 : 1, 5, 79, 395
521 : 1, 521
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 309,869,395,521, is 1.
Now, the common factors can be found like this.
309:3x 103
869:11x 79
395:5x 79
521:521
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
79 = 79
Therefore, the value for common factors is 79.
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 = 55260279195/(1x79)
LCM = 55260279195/79
LCM = 699497205
Thus, we can understand that the LCM of 309,869,395,521 is 699497205.
