Given numbers are 732,172,738,892
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 732,172,738,892 is 863355204.
Find LCM of 732,172,738,892 with Prime Factorization
| 2 | 732, 172, 738, 892 |
| 2 | 366, 86, 369, 446 |
| 3 | 183, 43, 369, 223 |
| 61, 43, 123, 223 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 61 x 43 x 123 x 223 = 863355204
Therefore, the lowest common multiple of 732,172,738,892 is 863355204.
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.
732 x 172 x 738 x 892 = 82882099584
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.
732 : 1, 2, 3, 4, 6, 12, 61, 122, 183, 244, 366, 732
172 : 1, 2, 4, 43, 86, 172
738 : 1, 2, 3, 6, 9, 18, 41, 82, 123, 246, 369, 738
892 : 1, 2, 4, 223, 446, 892
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 732,172,738,892, is 2.
Now, the common factors can be found like this.
732:2x 2x 3x 61
172:2x 2x 43
738:2x 3x 3x 41
892:2x 2x 223
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 2x 2x 3 = 48
Therefore, the value for common factors is 48.
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 = 82882099584/(2x48)
LCM = 82882099584/96
LCM = 863355204
Thus, we can understand that the LCM of 732,172,738,892 is 863355204.
