Given numbers are 397,478,120,429,239
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 397,478,120,429,239 is 1628192280.
Find LCM of 397,478,120,429,239 with Prime Factorization
| 2 | 397, 478, 120, 429, 239 |
| 3 | 397, 239, 60, 429, 239 |
| 239 | 397, 239, 20, 143, 239 |
| 397, 1, 20, 143, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 239 x 397 x 1 x 20 x 143 x 1 = 1628192280
Therefore, the lowest common multiple of 397,478,120,429,239 is 1628192280.
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.
397 x 478 x 120 x 429 x 239 = 2334827729520
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.
397 : 1, 397
478 : 1, 2, 239, 478
120 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, 120
429 : 1, 3, 11, 13, 33, 39, 143, 429
239 : 1, 239
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 397,478,120,429,239, is 1.
Now, the common factors can be found like this.
397:397
478:2x 239
120:2x 2x 2x 3x 5
429:3x 11x 13
239:239
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 239 = 1434
Therefore, the value for common factors is 1434.
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 = 2334827729520/(1x1434)
LCM = 2334827729520/1434
LCM = 1628192280
Thus, we can understand that the LCM of 397,478,120,429,239 is 1628192280.
