Find LCM of 315,871,621,353,644 with Prime Factorization
| 3 | 315, 871, 621, 353, 644 |
| 3 | 105, 871, 207, 353, 644 |
| 7 | 35, 871, 69, 353, 644 |
| 23 | 5, 871, 69, 353, 92 |
| 5, 871, 3, 353, 4 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 7 x 23 x 5 x 871 x 3 x 353 x 4 = 26730833220
Therefore, the lowest common multiple of 315,871,621,353,644 is 26730833220.
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.
315 x 871 x 621 x 353 x 644 = 38732977335780
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.
315 : 1, 3, 5, 7, 9, 15, 21, 35, 45, 63, 105, 315
871 : 1, 13, 67, 871
621 : 1, 3, 9, 23, 27, 69, 207, 621
353 : 1, 353
644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 315,871,621,353,644, is 1.
Now, the common factors can be found like this.
315:3x 3x 5x 7
871:13x 67
621:3x 3x 3x 23
353:353
644:2x 2x 7x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 7x 23 = 1449
Therefore, the value for common factors is 1449.
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 = 38732977335780/(1x1449)
LCM = 38732977335780/1449
LCM = 26730833220
Thus, we can understand that the LCM of 315,871,621,353,644 is 26730833220.
