Given numbers are 131,991,401,786
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 131,991,401,786 is 312349326.
Find LCM of 131,991,401,786 with Prime Factorization
131 | 131, 991, 401, 786 |
1, 991, 401, 6 |
Multiply the prime numbers at the bottom and the left side.
131 x 1 x 991 x 401 x 6 = 312349326
Therefore, the lowest common multiple of 131,991,401,786 is 312349326.
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.
131 x 991 x 401 x 786 = 40917761706
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.
131 : 1, 131
991 : 1, 991
401 : 1, 401
786 : 1, 2, 3, 6, 131, 262, 393, 786
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 131,991,401,786, is 1.
Now, the common factors can be found like this.
131:131
991:991
401:401
786:2x 3x 131
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
131 = 131
Therefore, the value for common factors is 131.
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 = 40917761706/(1x131)
LCM = 40917761706/131
LCM = 312349326
Thus, we can understand that the LCM of 131,991,401,786 is 312349326.
