Given numbers are 418,401,889,763
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 418,401,889,763 is 16242351818.
Find LCM of 418,401,889,763 with Prime Factorization
| 7 | 418, 401, 889, 763 |
| 418, 401, 127, 109 |
Multiply the prime numbers at the bottom and the left side.
7 x 418 x 401 x 127 x 109 = 16242351818
Therefore, the lowest common multiple of 418,401,889,763 is 16242351818.
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.
418 x 401 x 889 x 763 = 113696462726
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.
418 : 1, 2, 11, 19, 22, 38, 209, 418
401 : 1, 401
889 : 1, 7, 127, 889
763 : 1, 7, 109, 763
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 418,401,889,763, is 1.
Now, the common factors can be found like this.
418:2x 11x 19
401:401
889:7x 127
763:7x 109
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
7 = 7
Therefore, the value for common factors is 7.
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 = 113696462726/(1x7)
LCM = 113696462726/7
LCM = 16242351818
Thus, we can understand that the LCM of 418,401,889,763 is 16242351818.
