Given numbers are 391,759,188,946
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 391,759,188,946 is 104307852.
Find LCM of 391,759,188,946 with Prime Factorization
2 | 391, 759, 188, 946 |
11 | 391, 759, 94, 473 |
23 | 391, 69, 94, 43 |
17, 3, 94, 43 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 23 x 17 x 3 x 94 x 43 = 104307852
Therefore, the lowest common multiple of 391,759,188,946 is 104307852.
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.
391 x 759 x 188 x 946 = 52779773112
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.
391 : 1, 17, 23, 391
759 : 1, 3, 11, 23, 33, 69, 253, 759
188 : 1, 2, 4, 47, 94, 188
946 : 1, 2, 11, 22, 43, 86, 473, 946
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 391,759,188,946, is 1.
Now, the common factors can be found like this.
391:17x 23
759:3x 11x 23
188:2x 2x 47
946:2x 11x 43
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 11x 23 = 506
Therefore, the value for common factors is 506.
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 = 52779773112/(1x506)
LCM = 52779773112/506
LCM = 104307852
Thus, we can understand that the LCM of 391,759,188,946 is 104307852.
