Given numbers are 391,962,794,957
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 391,962,794,957 is 142907253918.
Find LCM of 391,962,794,957 with Prime Factorization
2 | 391, 962, 794, 957 |
391, 481, 397, 957 |
Multiply the prime numbers at the bottom and the left side.
2 x 391 x 481 x 397 x 957 = 142907253918
Therefore, the lowest common multiple of 391,962,794,957 is 142907253918.
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 962 x 794 x 957 = 285814507836
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
962 : 1, 2, 13, 26, 37, 74, 481, 962
794 : 1, 2, 397, 794
957 : 1, 3, 11, 29, 33, 87, 319, 957
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 391,962,794,957, is 1.
Now, the common factors can be found like this.
391:17x 23
962:2x 13x 37
794:2x 397
957:3x 11x 29
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2 = 2
Therefore, the value for common factors is 2.
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 = 285814507836/(1x2)
LCM = 285814507836/2
LCM = 142907253918
Thus, we can understand that the LCM of 391,962,794,957 is 142907253918.
