Given numbers are 689,174,771,117,443
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 689,174,771,117,443 is 40947422958.
Find LCM of 689,174,771,117,443 with Prime Factorization
| 3 | 689, 174, 771, 117, 443 |
| 13 | 689, 58, 257, 39, 443 |
| 53, 58, 257, 3, 443 |
Multiply the prime numbers at the bottom and the left side.
3 x 13 x 53 x 58 x 257 x 3 x 443 = 40947422958
Therefore, the lowest common multiple of 689,174,771,117,443 is 40947422958.
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.
689 x 174 x 771 x 117 x 443 = 4790848486086
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.
689 : 1, 13, 53, 689
174 : 1, 2, 3, 6, 29, 58, 87, 174
771 : 1, 3, 257, 771
117 : 1, 3, 9, 13, 39, 117
443 : 1, 443
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 689,174,771,117,443, is 1.
Now, the common factors can be found like this.
689:13x 53
174:2x 3x 29
771:3x 257
117:3x 3x 13
443:443
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 13 = 117
Therefore, the value for common factors is 117.
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 = 4790848486086/(1x117)
LCM = 4790848486086/117
LCM = 40947422958
Thus, we can understand that the LCM of 689,174,771,117,443 is 40947422958.
