Given numbers are 538,445,399,747
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 538,445,399,747 is 23785622910.
Find LCM of 538,445,399,747 with Prime Factorization
3 | 538, 445, 399, 747 |
538, 445, 133, 249 |
Multiply the prime numbers at the bottom and the left side.
3 x 538 x 445 x 133 x 249 = 23785622910
Therefore, the lowest common multiple of 538,445,399,747 is 23785622910.
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.
538 x 445 x 399 x 747 = 71356868730
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.
538 : 1, 2, 269, 538
445 : 1, 5, 89, 445
399 : 1, 3, 7, 19, 21, 57, 133, 399
747 : 1, 3, 9, 83, 249, 747
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 538,445,399,747, is 1.
Now, the common factors can be found like this.
538:2x 269
445:5x 89
399:3x 7x 19
747:3x 3x 83
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3 = 3
Therefore, the value for common factors is 3.
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 = 71356868730/(1x3)
LCM = 71356868730/3
LCM = 23785622910
Thus, we can understand that the LCM of 538,445,399,747 is 23785622910.
