Given numbers are 898,802,657,401
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 898,802,657,401 is 236584386.
Find LCM of 898,802,657,401 with Prime Factorization
| 2 | 898, 802, 657, 401 |
| 401 | 449, 401, 657, 401 |
| 449, 1, 657, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 401 x 449 x 1 x 657 x 1 = 236584386
Therefore, the lowest common multiple of 898,802,657,401 is 236584386.
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.
898 x 802 x 657 x 401 = 189740677572
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.
898 : 1, 2, 449, 898
802 : 1, 2, 401, 802
657 : 1, 3, 9, 73, 219, 657
401 : 1, 401
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 898,802,657,401, is 1.
Now, the common factors can be found like this.
898:2x 449
802:2x 401
657:3x 3x 73
401:401
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 401 = 802
Therefore, the value for common factors is 802.
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 = 189740677572/(1x802)
LCM = 189740677572/802
LCM = 236584386
Thus, we can understand that the LCM of 898,802,657,401 is 236584386.
