Given numbers are 474,641,201,402
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 474,641,201,402 is 20356878.
Find LCM of 474,641,201,402 with Prime Factorization
| 2 | 474, 641, 201, 402 |
| 3 | 237, 641, 201, 201 |
| 67 | 79, 641, 67, 67 |
| 79, 641, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 67 x 79 x 641 x 1 x 1 = 20356878
Therefore, the lowest common multiple of 474,641,201,402 is 20356878.
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.
474 x 641 x 201 x 402 = 24550394868
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.
474 : 1, 2, 3, 6, 79, 158, 237, 474
641 : 1, 641
201 : 1, 3, 67, 201
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 474,641,201,402, is 1.
Now, the common factors can be found like this.
474:2x 3x 79
641:641
201:3x 67
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 3x 67 = 1206
Therefore, the value for common factors is 1206.
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 = 24550394868/(1x1206)
LCM = 24550394868/1206
LCM = 20356878
Thus, we can understand that the LCM of 474,641,201,402 is 20356878.
