Given numbers are 628,871,843,402
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 628,871,843,402 is 461110884.
Find LCM of 628,871,843,402 with Prime Factorization
| 2 | 628, 871, 843, 402 |
| 3 | 314, 871, 843, 201 |
| 67 | 314, 871, 281, 67 |
| 314, 13, 281, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 67 x 314 x 13 x 281 x 1 = 461110884
Therefore, the lowest common multiple of 628,871,843,402 is 461110884.
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.
628 x 871 x 843 x 402 = 185366575368
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.
628 : 1, 2, 4, 157, 314, 628
871 : 1, 13, 67, 871
843 : 1, 3, 281, 843
402 : 1, 2, 3, 6, 67, 134, 201, 402
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 628,871,843,402, is 1.
Now, the common factors can be found like this.
628:2x 2x 157
871:13x 67
843:3x 281
402:2x 3x 67
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 67 = 402
Therefore, the value for common factors is 402.
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 = 185366575368/(1x402)
LCM = 185366575368/402
LCM = 461110884
Thus, we can understand that the LCM of 628,871,843,402 is 461110884.
