Given numbers are 745,458,945,175
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 745,458,945,175 is 322443450.
Find LCM of 745,458,945,175 with Prime Factorization
| 5 | 745, 458, 945, 175 |
| 7 | 149, 458, 189, 35 |
| 149, 458, 27, 5 |
Multiply the prime numbers at the bottom and the left side.
5 x 7 x 149 x 458 x 27 x 5 = 322443450
Therefore, the lowest common multiple of 745,458,945,175 is 322443450.
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.
745 x 458 x 945 x 175 = 56427603750
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.
745 : 1, 5, 149, 745
458 : 1, 2, 229, 458
945 : 1, 3, 5, 7, 9, 15, 21, 27, 35, 45, 63, 105, 135, 189, 315, 945
175 : 1, 5, 7, 25, 35, 175
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 745,458,945,175, is 1.
Now, the common factors can be found like this.
745:5x 149
458:2x 229
945:3x 3x 3x 5x 7
175:5x 5x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5x 5x 7 = 175
Therefore, the value for common factors is 175.
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 = 56427603750/(1x175)
LCM = 56427603750/175
LCM = 322443450
Thus, we can understand that the LCM of 745,458,945,175 is 322443450.
