Given numbers are 402,670,871,672
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 402,670,871,672 is 2926560.
Find LCM of 402,670,871,672 with Prime Factorization
| 2 | 402, 670, 871, 672 |
| 3 | 201, 335, 871, 336 |
| 67 | 67, 335, 871, 112 |
| 1, 5, 13, 112 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 67 x 1 x 5 x 13 x 112 = 2926560
Therefore, the lowest common multiple of 402,670,871,672 is 2926560.
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.
402 x 670 x 871 x 672 = 157647934080
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.
402 : 1, 2, 3, 6, 67, 134, 201, 402
670 : 1, 2, 5, 10, 67, 134, 335, 670
871 : 1, 13, 67, 871
672 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 16, 21, 24, 28, 32, 42, 48, 56, 84, 96, 112, 168, 224, 336, 672
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 402,670,871,672, is 1.
Now, the common factors can be found like this.
402:2x 3x 67
670:2x 5x 67
871:13x 67
672:2x 2x 2x 2x 2x 3x 7
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 3x 67x 67 = 53868
Therefore, the value for common factors is 53868.
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 = 157647934080/(1x53868)
LCM = 157647934080/53868
LCM = 2926560
Thus, we can understand that the LCM of 402,670,871,672 is 2926560.
