Given numbers are 397,506,869,338
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 397,506,869,338 is 2681975582.
Find LCM of 397,506,869,338 with Prime Factorization
| 2 | 397, 506, 869, 338 |
| 11 | 397, 253, 869, 169 |
| 397, 23, 79, 169 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 397 x 23 x 79 x 169 = 2681975582
Therefore, the lowest common multiple of 397,506,869,338 is 2681975582.
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 506 x 869 x 338 = 59003462804
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
506 : 1, 2, 11, 22, 23, 46, 253, 506
869 : 1, 11, 79, 869
338 : 1, 2, 13, 26, 169, 338
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 397,506,869,338, is 1.
Now, the common factors can be found like this.
397:397
506:2x 11x 23
869:11x 79
338:2x 13x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 11 = 22
Therefore, the value for common factors is 22.
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 = 59003462804/(1x22)
LCM = 59003462804/22
LCM = 2681975582
Thus, we can understand that the LCM of 397,506,869,338 is 2681975582.
