Given numbers are 474,721,316,434
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 474,721,316,434 is 21188748.
Find LCM of 474,721,316,434 with Prime Factorization
| 2 | 474, 721, 316, 434 |
| 7 | 237, 721, 158, 217 |
| 79 | 237, 103, 158, 31 |
| 3, 103, 2, 31 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 79 x 3 x 103 x 2 x 31 = 21188748
Therefore, the lowest common multiple of 474,721,316,434 is 21188748.
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 721 x 316 x 434 = 46869510576
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
721 : 1, 7, 103, 721
316 : 1, 2, 4, 79, 158, 316
434 : 1, 2, 7, 14, 31, 62, 217, 434
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 474,721,316,434, is 1.
Now, the common factors can be found like this.
474:2x 3x 79
721:7x 103
316:2x 2x 79
434:2x 7x 31
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 7x 79 = 2212
Therefore, the value for common factors is 2212.
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 = 46869510576/(1x2212)
LCM = 46869510576/2212
LCM = 21188748
Thus, we can understand that the LCM of 474,721,316,434 is 21188748.
