Given numbers are 156,209,385,385
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 156,209,385,385 is 1141140.
Find LCM of 156,209,385,385 with Prime Factorization
5 | 156, 209, 385, 385 |
7 | 156, 209, 77, 77 |
11 | 156, 209, 11, 11 |
156, 19, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
5 x 7 x 11 x 156 x 19 x 1 x 1 = 1141140
Therefore, the lowest common multiple of 156,209,385,385 is 1141140.
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.
156 x 209 x 385 x 385 = 4832727900
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.
156 : 1, 2, 3, 4, 6, 12, 13, 26, 39, 52, 78, 156
209 : 1, 11, 19, 209
385 : 1, 5, 7, 11, 35, 55, 77, 385
385 : 1, 5, 7, 11, 35, 55, 77, 385
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 156,209,385,385, is 1.
Now, the common factors can be found like this.
156:2x 2x 3x 13
209:11x 19
385:5x 7x 11
385:5x 7x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5x 7x 11x 11 = 4235
Therefore, the value for common factors is 4235.
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 = 4832727900/(1x4235)
LCM = 4832727900/4235
LCM = 1141140
Thus, we can understand that the LCM of 156,209,385,385 is 1141140.
