Given numbers are 871,309,412,292
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 871,309,412,292 is 78588588.
Find LCM of 871,309,412,292 with Prime Factorization
| 2 | 871, 309, 412, 292 |
| 2 | 871, 309, 206, 146 |
| 103 | 871, 309, 103, 73 |
| 871, 3, 1, 73 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 103 x 871 x 3 x 1 x 73 = 78588588
Therefore, the lowest common multiple of 871,309,412,292 is 78588588.
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.
871 x 309 x 412 x 292 = 32378498256
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.
871 : 1, 13, 67, 871
309 : 1, 3, 103, 309
412 : 1, 2, 4, 103, 206, 412
292 : 1, 2, 4, 73, 146, 292
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 871,309,412,292, is 1.
Now, the common factors can be found like this.
871:13x 67
309:3x 103
412:2x 2x 103
292:2x 2x 73
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 103 = 412
Therefore, the value for common factors is 412.
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 = 32378498256/(1x412)
LCM = 32378498256/412
LCM = 78588588
Thus, we can understand that the LCM of 871,309,412,292 is 78588588.
