Given numbers are 425,900,961,170
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 425,900,961,170 is 14703300.
Find LCM of 425,900,961,170 with Prime Factorization
| 2 | 425, 900, 961, 170 |
| 5 | 425, 450, 961, 85 |
| 5 | 17, 90, 961, 85 |
| 17 | 17, 18, 961, 17 |
| 1, 18, 961, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 5 x 17 x 1 x 18 x 961 x 1 = 14703300
Therefore, the lowest common multiple of 425,900,961,170 is 14703300.
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.
425 x 900 x 961 x 170 = 62489025000
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.
425 : 1, 5, 17, 25, 85, 425
900 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 25, 30, 36, 45, 50, 60, 75, 90, 100, 150, 180, 225, 300, 450, 900
961 : 1, 31, 961
170 : 1, 2, 5, 10, 17, 34, 85, 170
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 425,900,961,170, is 1.
Now, the common factors can be found like this.
425:5x 5x 17
900:2x 2x 3x 3x 5x 5
961:31x 31
170:2x 5x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 5x 5x 17 = 4250
Therefore, the value for common factors is 4250.
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 = 62489025000/(1x4250)
LCM = 62489025000/4250
LCM = 14703300
Thus, we can understand that the LCM of 425,900,961,170 is 14703300.
