Given numbers are 211,686,991,422
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 211,686,991,422 is 143443286.
Find LCM of 211,686,991,422 with Prime Factorization
2 | 211, 686, 991, 422 |
211 | 211, 343, 991, 211 |
1, 343, 991, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 211 x 1 x 343 x 991 x 1 = 143443286
Therefore, the lowest common multiple of 211,686,991,422 is 143443286.
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.
211 x 686 x 991 x 422 = 60533066692
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.
211 : 1, 211
686 : 1, 2, 7, 14, 49, 98, 343, 686
991 : 1, 991
422 : 1, 2, 211, 422
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 211,686,991,422, is 1.
Now, the common factors can be found like this.
211:211
686:2x 7x 7x 7
991:991
422:2x 211
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 211 = 422
Therefore, the value for common factors is 422.
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 = 60533066692/(1x422)
LCM = 60533066692/422
LCM = 143443286
Thus, we can understand that the LCM of 211,686,991,422 is 143443286.
