Given numbers are 745,172,844,529,945
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 745,172,844,529,945 is 2703240286740.
Find LCM of 745,172,844,529,945 with Prime Factorization
| 2 | 745, 172, 844, 529, 945 |
| 2 | 745, 86, 422, 529, 945 |
| 5 | 745, 43, 211, 529, 945 |
| 149, 43, 211, 529, 189 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 149 x 43 x 211 x 529 x 189 = 2703240286740
Therefore, the lowest common multiple of 745,172,844,529,945 is 2703240286740.
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 172 x 844 x 529 x 945 = 54064805734800
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
172 : 1, 2, 4, 43, 86, 172
844 : 1, 2, 4, 211, 422, 844
529 : 1, 23, 529
945 : 1, 3, 5, 7, 9, 15, 21, 27, 35, 45, 63, 105, 135, 189, 315, 945
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 745,172,844,529,945, is 1.
Now, the common factors can be found like this.
745:5x 149
172:2x 2x 43
844:2x 2x 211
529:23x 23
945:3x 3x 3x 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.
2x 2x 5 = 20
Therefore, the value for common factors is 20.
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 = 54064805734800/(1x20)
LCM = 54064805734800/20
LCM = 2703240286740
Thus, we can understand that the LCM of 745,172,844,529,945 is 2703240286740.
