Given numbers are 401,743,637,401,355
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 401,743,637,401,355 is 67375340305.
Find LCM of 401,743,637,401,355 with Prime Factorization
| 401 | 401, 743, 637, 401, 355 |
| 1, 743, 637, 1, 355 |
Multiply the prime numbers at the bottom and the left side.
401 x 1 x 743 x 637 x 1 x 355 = 67375340305
Therefore, the lowest common multiple of 401,743,637,401,355 is 67375340305.
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.
401 x 743 x 637 x 401 x 355 = 27017511462305
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.
401 : 1, 401
743 : 1, 743
637 : 1, 7, 13, 49, 91, 637
401 : 1, 401
355 : 1, 5, 71, 355
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 401,743,637,401,355, is 1.
Now, the common factors can be found like this.
401:401
743:743
637:7x 7x 13
401:401
355:5x 71
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
401 = 401
Therefore, the value for common factors is 401.
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 = 27017511462305/(1x401)
LCM = 27017511462305/401
LCM = 67375340305
Thus, we can understand that the LCM of 401,743,637,401,355 is 67375340305.
