Given numbers are 285,762,435,889
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 285,762,435,889 is 14695170.
Find LCM of 285,762,435,889 with Prime Factorization
| 3 | 285, 762, 435, 889 |
| 5 | 95, 254, 145, 889 |
| 127 | 19, 254, 29, 889 |
| 19, 2, 29, 7 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 127 x 19 x 2 x 29 x 7 = 14695170
Therefore, the lowest common multiple of 285,762,435,889 is 14695170.
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.
285 x 762 x 435 x 889 = 83982896550
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.
285 : 1, 3, 5, 15, 19, 57, 95, 285
762 : 1, 2, 3, 6, 127, 254, 381, 762
435 : 1, 3, 5, 15, 29, 87, 145, 435
889 : 1, 7, 127, 889
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 285,762,435,889, is 1.
Now, the common factors can be found like this.
285:3x 5x 19
762:2x 3x 127
435:3x 5x 29
889:7x 127
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 127 = 5715
Therefore, the value for common factors is 5715.
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 = 83982896550/(1x5715)
LCM = 83982896550/5715
LCM = 14695170
Thus, we can understand that the LCM of 285,762,435,889 is 14695170.
