Given numbers are 397,684,551,754
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 397,684,551,754 is 102373596.
Find LCM of 397,684,551,754 with Prime Factorization
| 2 | 397, 684, 551, 754 |
| 19 | 397, 342, 551, 377 |
| 29 | 397, 18, 29, 377 |
| 397, 18, 1, 13 |
Multiply the prime numbers at the bottom and the left side.
2 x 19 x 29 x 397 x 18 x 1 x 13 = 102373596
Therefore, the lowest common multiple of 397,684,551,754 is 102373596.
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 684 x 551 x 754 = 112815702792
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
684 : 1, 2, 3, 4, 6, 9, 12, 18, 19, 36, 38, 57, 76, 114, 171, 228, 342, 684
551 : 1, 19, 29, 551
754 : 1, 2, 13, 26, 29, 58, 377, 754
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 397,684,551,754, is 1.
Now, the common factors can be found like this.
397:397
684:2x 2x 3x 3x 19
551:19x 29
754:2x 13x 29
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 19x 29 = 1102
Therefore, the value for common factors is 1102.
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 = 112815702792/(1x1102)
LCM = 112815702792/1102
LCM = 102373596
Thus, we can understand that the LCM of 397,684,551,754 is 102373596.
