Given numbers are 1,676,169,261
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 1,676,169,261 is 176436.
Find LCM of 1,676,169,261 with Prime Factorization
13 | 1, 676, 169, 261 |
13 | 1, 52, 13, 261 |
1, 4, 1, 261 |
Multiply the prime numbers at the bottom and the left side.
13 x 13 x 1 x 4 x 1 x 261 = 176436
Therefore, the lowest common multiple of 1,676,169,261 is 176436.
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.
1 x 676 x 169 x 261 = 29817684
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.
1 : 1
676 : 1, 2, 4, 13, 26, 52, 169, 338, 676
169 : 1, 13, 169
261 : 1, 3, 9, 29, 87, 261
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 1,676,169,261, is 1.
Now, the common factors can be found like this.
1:
676:2x 2x 13x 13
169:13x 13
261:3x 3x 29
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 = 29817684/(1x169)
LCM = 29817684/169
LCM = 176436
Thus, we can understand that the LCM of 1,676,169,261 is 176436.
Here are some samples of LCM of two or more Numbers calculations.
