Given numbers are 901,477,225,636
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 901,477,225,636 is 810900.
Find LCM of 901,477,225,636 with Prime Factorization
| 3 | 901, 477, 225, 636 |
| 3 | 901, 159, 75, 212 |
| 53 | 901, 53, 25, 212 |
| 17, 1, 25, 4 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 53 x 17 x 1 x 25 x 4 = 810900
Therefore, the lowest common multiple of 901,477,225,636 is 810900.
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.
901 x 477 x 225 x 636 = 61501088700
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.
901 : 1, 17, 53, 901
477 : 1, 3, 9, 53, 159, 477
225 : 1, 3, 5, 9, 15, 25, 45, 75, 225
636 : 1, 2, 3, 4, 6, 12, 53, 106, 159, 212, 318, 636
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 901,477,225,636, is 1.
Now, the common factors can be found like this.
901:17x 53
477:3x 3x 53
225:3x 3x 5x 5
636:2x 2x 3x 53
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 3x 53x 53 = 75843
Therefore, the value for common factors is 75843.
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 = 61501088700/(1x75843)
LCM = 61501088700/75843
LCM = 810900
Thus, we can understand that the LCM of 901,477,225,636 is 810900.
