Given numbers are 686,851,569,148,769
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 686,851,569,148,769 is 510883971892.
Find LCM of 686,851,569,148,769 with Prime Factorization
| 2 | 686, 851, 569, 148, 769 |
| 37 | 343, 851, 569, 74, 769 |
| 343, 23, 569, 2, 769 |
Multiply the prime numbers at the bottom and the left side.
2 x 37 x 343 x 23 x 569 x 2 x 769 = 510883971892
Therefore, the lowest common multiple of 686,851,569,148,769 is 510883971892.
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.
686 x 851 x 569 x 148 x 769 = 37805413920008
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.
686 : 1, 2, 7, 14, 49, 98, 343, 686
851 : 1, 23, 37, 851
569 : 1, 569
148 : 1, 2, 4, 37, 74, 148
769 : 1, 769
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 686,851,569,148,769, is 1.
Now, the common factors can be found like this.
686:2x 7x 7x 7
851:23x 37
569:569
148:2x 2x 37
769:769
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 37 = 74
Therefore, the value for common factors is 74.
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 = 37805413920008/(1x74)
LCM = 37805413920008/74
LCM = 510883971892
Thus, we can understand that the LCM of 686,851,569,148,769 is 510883971892.
