Given numbers are 871,748,535,170
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 871,748,535,170 is 348556780.
Find LCM of 871,748,535,170 with Prime Factorization
| 2 | 871, 748, 535, 170 |
| 5 | 871, 374, 535, 85 |
| 17 | 871, 374, 107, 17 |
| 871, 22, 107, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 17 x 871 x 22 x 107 x 1 = 348556780
Therefore, the lowest common multiple of 871,748,535,170 is 348556780.
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 748 x 535 x 170 = 59254652600
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
748 : 1, 2, 4, 11, 17, 22, 34, 44, 68, 187, 374, 748
535 : 1, 5, 107, 535
170 : 1, 2, 5, 10, 17, 34, 85, 170
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 871,748,535,170, is 1.
Now, the common factors can be found like this.
871:13x 67
748:2x 2x 11x 17
535:5x 107
170:2x 5x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 17 = 170
Therefore, the value for common factors is 170.
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 = 59254652600/(1x170)
LCM = 59254652600/170
LCM = 348556780
Thus, we can understand that the LCM of 871,748,535,170 is 348556780.
