Given numbers are 263,871,648,390
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 263,871,648,390 is 742196520.
Find LCM of 263,871,648,390 with Prime Factorization
| 2 | 263, 871, 648, 390 |
| 3 | 263, 871, 324, 195 |
| 13 | 263, 871, 108, 65 |
| 263, 67, 108, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 13 x 263 x 67 x 108 x 5 = 742196520
Therefore, the lowest common multiple of 263,871,648,390 is 742196520.
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.
263 x 871 x 648 x 390 = 57891328560
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.
263 : 1, 263
871 : 1, 13, 67, 871
648 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 81, 108, 162, 216, 324, 648
390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 263,871,648,390, is 1.
Now, the common factors can be found like this.
263:263
871:13x 67
648:2x 2x 2x 3x 3x 3x 3
390:2x 3x 5x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 13 = 78
Therefore, the value for common factors is 78.
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 = 57891328560/(1x78)
LCM = 57891328560/78
LCM = 742196520
Thus, we can understand that the LCM of 263,871,648,390 is 742196520.
