Given numbers are 474,101,693,385
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 474,101,693,385 is 55294470.
Find LCM of 474,101,693,385 with Prime Factorization
| 3 | 474, 101, 693, 385 |
| 7 | 158, 101, 231, 385 |
| 11 | 158, 101, 33, 55 |
| 158, 101, 3, 5 |
Multiply the prime numbers at the bottom and the left side.
3 x 7 x 11 x 158 x 101 x 3 x 5 = 55294470
Therefore, the lowest common multiple of 474,101,693,385 is 55294470.
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.
474 x 101 x 693 x 385 = 12773022570
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.
474 : 1, 2, 3, 6, 79, 158, 237, 474
101 : 1, 101
693 : 1, 3, 7, 9, 11, 21, 33, 63, 77, 99, 231, 693
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 474,101,693,385, is 1.
Now, the common factors can be found like this.
474:2x 3x 79
101:101
693:3x 3x 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.
3x 7x 11 = 231
Therefore, the value for common factors is 231.
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 = 12773022570/(1x231)
LCM = 12773022570/231
LCM = 55294470
Thus, we can understand that the LCM of 474,101,693,385 is 55294470.
