Given numbers are 661,105,985,578,315
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 661,105,985,578,315 is 23708609190.
Find LCM of 661,105,985,578,315 with Prime Factorization
3 | 661, 105, 985, 578, 315 |
5 | 661, 35, 985, 578, 105 |
7 | 661, 7, 197, 578, 21 |
661, 1, 197, 578, 3 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 7 x 661 x 1 x 197 x 578 x 3 = 23708609190
Therefore, the lowest common multiple of 661,105,985,578,315 is 23708609190.
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.
661 x 105 x 985 x 578 x 315 = 12447019824750
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.
661 : 1, 661
105 : 1, 3, 5, 7, 15, 21, 35, 105
985 : 1, 5, 197, 985
578 : 1, 2, 17, 34, 289, 578
315 : 1, 3, 5, 7, 9, 15, 21, 35, 45, 63, 105, 315
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 661,105,985,578,315, is 1.
Now, the common factors can be found like this.
661:661
105:3x 5x 7
985:5x 197
578:2x 17x 17
315:3x 3x 5x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 5x 5x 7 = 525
Therefore, the value for common factors is 525.
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 = 12447019824750/(1x525)
LCM = 12447019824750/525
LCM = 23708609190
Thus, we can understand that the LCM of 661,105,985,578,315 is 23708609190.
