Given numbers are 738,874,724,494
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 738,874,724,494 is 1517713236.
Find LCM of 738,874,724,494 with Prime Factorization
| 2 | 738, 874, 724, 494 |
| 19 | 369, 437, 362, 247 |
| 369, 23, 362, 13 |
Multiply the prime numbers at the bottom and the left side.
2 x 19 x 369 x 23 x 362 x 13 = 1517713236
Therefore, the lowest common multiple of 738,874,724,494 is 1517713236.
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.
738 x 874 x 724 x 494 = 230692411872
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.
738 : 1, 2, 3, 6, 9, 18, 41, 82, 123, 246, 369, 738
874 : 1, 2, 19, 23, 38, 46, 437, 874
724 : 1, 2, 4, 181, 362, 724
494 : 1, 2, 13, 19, 26, 38, 247, 494
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 738,874,724,494, is 2.
Now, the common factors can be found like this.
738:2x 3x 3x 41
874:2x 19x 23
724:2x 2x 181
494:2x 13x 19
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 19 = 76
Therefore, the value for common factors is 76.
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 = 230692411872/(2x76)
LCM = 230692411872/152
LCM = 1517713236
Thus, we can understand that the LCM of 738,874,724,494 is 1517713236.
