Given numbers are 475,507,285,438
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 475,507,285,438 is 35160450.
Find LCM of 475,507,285,438 with Prime Factorization
| 3 | 475, 507, 285, 438 |
| 5 | 475, 169, 95, 146 |
| 19 | 19, 169, 95, 146 |
| 1, 169, 5, 146 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 19 x 1 x 169 x 5 x 146 = 35160450
Therefore, the lowest common multiple of 475,507,285,438 is 35160450.
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.
475 x 507 x 285 x 438 = 30062184750
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.
475 : 1, 5, 19, 25, 95, 475
507 : 1, 3, 13, 39, 169, 507
285 : 1, 3, 5, 15, 19, 57, 95, 285
438 : 1, 2, 3, 6, 73, 146, 219, 438
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 475,507,285,438, is 1.
Now, the common factors can be found like this.
475:5x 5x 19
507:3x 13x 13
285:3x 5x 19
438:2x 3x 73
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 5x 19 = 855
Therefore, the value for common factors is 855.
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 = 30062184750/(1x855)
LCM = 30062184750/855
LCM = 35160450
Thus, we can understand that the LCM of 475,507,285,438 is 35160450.
