Given numbers are 401,646,973,950
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 401,646,973,950 is 6301293950.
Find LCM of 401,646,973,950 with Prime Factorization
| 2 | 401, 646, 973, 950 |
| 19 | 401, 323, 973, 475 |
| 401, 17, 973, 25 |
Multiply the prime numbers at the bottom and the left side.
2 x 19 x 401 x 17 x 973 x 25 = 6301293950
Therefore, the lowest common multiple of 401,646,973,950 is 6301293950.
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 646 x 973 x 950 = 239449170100
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
646 : 1, 2, 17, 19, 34, 38, 323, 646
973 : 1, 7, 139, 973
950 : 1, 2, 5, 10, 19, 25, 38, 50, 95, 190, 475, 950
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 401,646,973,950, is 1.
Now, the common factors can be found like this.
401:401
646:2x 17x 19
973:7x 139
950:2x 5x 5x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 19 = 38
Therefore, the value for common factors is 38.
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 = 239449170100/(1x38)
LCM = 239449170100/38
LCM = 6301293950
Thus, we can understand that the LCM of 401,646,973,950 is 6301293950.
