Given numbers are 729,745,119,971,447
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 729,745,119,971,447 is 62755239645.
Find LCM of 729,745,119,971,447 with Prime Factorization
| 3 | 729, 745, 119, 971, 447 |
| 149 | 243, 745, 119, 971, 149 |
| 243, 5, 119, 971, 1 |
Multiply the prime numbers at the bottom and the left side.
3 x 149 x 243 x 5 x 119 x 971 x 1 = 62755239645
Therefore, the lowest common multiple of 729,745,119,971,447 is 62755239645.
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.
729 x 745 x 119 x 971 x 447 = 28051592121315
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.
729 : 1, 3, 9, 27, 81, 243, 729
745 : 1, 5, 149, 745
119 : 1, 7, 17, 119
971 : 1, 971
447 : 1, 3, 149, 447
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 729,745,119,971,447, is 1.
Now, the common factors can be found like this.
729:3x 3x 3x 3x 3x 3
745:5x 149
119:7x 17
971:971
447:3x 149
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 149 = 447
Therefore, the value for common factors is 447.
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 = 28051592121315/(1x447)
LCM = 28051592121315/447
LCM = 62755239645
Thus, we can understand that the LCM of 729,745,119,971,447 is 62755239645.
