Given numbers are 72,916,928
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 72,916,928 is 1912608.
Find LCM of 72,916,928 with Prime Factorization
| 2 | 72, 916, 928 |
| 2 | 36, 458, 464 |
| 2 | 18, 229, 232 |
| 9, 229, 116 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 9 x 229 x 116 = 1912608
Therefore, the lowest common multiple of 72,916,928 is 1912608.
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.
72 x 916 x 928 = 61203456
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.
72 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36, 72
916 : 1, 2, 4, 229, 458, 916
928 : 1, 2, 4, 8, 16, 29, 32, 58, 116, 232, 464, 928
4 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 72,916,928, is 4.
Now, the common factors can be found like this.
72:2x 2x 2x 3x 3
916:2x 2x 229
928:2x 2x 2x 2x 2x 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 2x 2 = 8
Therefore, the value for common factors is 8.
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 = 61203456/(4x8)
LCM = 61203456/32
LCM = 1912608
Thus, we can understand that the LCM of 72,916,928 is 1912608.
