Given numbers are 327,763,390,905
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 327,763,390,905 is 53860170.
Find LCM of 327,763,390,905 with Prime Factorization
| 3 | 327, 763, 390, 905 |
| 5 | 109, 763, 130, 905 |
| 109 | 109, 763, 26, 181 |
| 1, 7, 26, 181 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 109 x 1 x 7 x 26 x 181 = 53860170
Therefore, the lowest common multiple of 327,763,390,905 is 53860170.
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.
327 x 763 x 390 x 905 = 88061377950
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.
327 : 1, 3, 109, 327
763 : 1, 7, 109, 763
390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390
905 : 1, 5, 181, 905
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 327,763,390,905, is 1.
Now, the common factors can be found like this.
327:3x 109
763:7x 109
390:2x 3x 5x 13
905:5x 181
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 109 = 1635
Therefore, the value for common factors is 1635.
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 = 88061377950/(1x1635)
LCM = 88061377950/1635
LCM = 53860170
Thus, we can understand that the LCM of 327,763,390,905 is 53860170.
