Given numbers are 689,299,821,442,271
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 689,299,821,442,271 is 119877705818.
Find LCM of 689,299,821,442,271 with Prime Factorization
| 13 | 689, 299, 821, 442, 271 |
| 53, 23, 821, 34, 271 |
Multiply the prime numbers at the bottom and the left side.
13 x 53 x 23 x 821 x 34 x 271 = 119877705818
Therefore, the lowest common multiple of 689,299,821,442,271 is 119877705818.
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 299 x 821 x 442 x 271 = 20259332283242
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
299 : 1, 13, 23, 299
821 : 1, 821
442 : 1, 2, 13, 17, 26, 34, 221, 442
271 : 1, 271
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 689,299,821,442,271, is 1.
Now, the common factors can be found like this.
689:13x 53
299:13x 23
821:821
442:2x 13x 17
271:271
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
13x 13 = 169
Therefore, the value for common factors is 169.
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 = 20259332283242/(1x169)
LCM = 20259332283242/169
LCM = 119877705818
Thus, we can understand that the LCM of 689,299,821,442,271 is 119877705818.
