Given numbers are 931,429,195,195
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 931,429,195,195 is 1996995.
Find LCM of 931,429,195,195 with Prime Factorization
| 3 | 931, 429, 195, 195 |
| 5 | 931, 143, 65, 65 |
| 13 | 931, 143, 13, 13 |
| 931, 11, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 13 x 931 x 11 x 1 x 1 = 1996995
Therefore, the lowest common multiple of 931,429,195,195 is 1996995.
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.
931 x 429 x 195 x 195 = 15187146975
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.
931 : 1, 7, 19, 49, 133, 931
429 : 1, 3, 11, 13, 33, 39, 143, 429
195 : 1, 3, 5, 13, 15, 39, 65, 195
195 : 1, 3, 5, 13, 15, 39, 65, 195
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 931,429,195,195, is 1.
Now, the common factors can be found like this.
931:7x 7x 19
429:3x 11x 13
195:3x 5x 13
195:3x 5x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 5x 13x 13 = 7605
Therefore, the value for common factors is 7605.
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 = 15187146975/(1x7605)
LCM = 15187146975/7605
LCM = 1996995
Thus, we can understand that the LCM of 931,429,195,195 is 1996995.
