Given numbers are 980,801,801,769
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 980,801,801,769 is 603649620.
Find LCM of 980,801,801,769 with Prime Factorization
| 3 | 980, 801, 801, 769 |
| 3 | 980, 267, 267, 769 |
| 89 | 980, 89, 89, 769 |
| 980, 1, 1, 769 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 89 x 980 x 1 x 1 x 769 = 603649620
Therefore, the lowest common multiple of 980,801,801,769 is 603649620.
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.
980 x 801 x 801 x 769 = 483523345620
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.
980 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 49, 70, 98, 140, 196, 245, 490, 980
801 : 1, 3, 9, 89, 267, 801
801 : 1, 3, 9, 89, 267, 801
769 : 1, 769
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 980,801,801,769, is 1.
Now, the common factors can be found like this.
980:2x 2x 5x 7x 7
801:3x 3x 89
801:3x 3x 89
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.
3x 3x 89 = 801
Therefore, the value for common factors is 801.
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 = 483523345620/(1x801)
LCM = 483523345620/801
LCM = 603649620
Thus, we can understand that the LCM of 980,801,801,769 is 603649620.
