Given numbers are 815,275,773,400
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 815,275,773,400 is 554395600.
Find LCM of 815,275,773,400 with Prime Factorization
5 | 815, 275, 773, 400 |
5 | 163, 55, 773, 80 |
163, 11, 773, 16 |
Multiply the prime numbers at the bottom and the left side.
5 x 5 x 163 x 11 x 773 x 16 = 554395600
Therefore, the lowest common multiple of 815,275,773,400 is 554395600.
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.
815 x 275 x 773 x 400 = 69299450000
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.
815 : 1, 5, 163, 815
275 : 1, 5, 11, 25, 55, 275
773 : 1, 773
400 : 1, 2, 4, 5, 8, 10, 16, 20, 25, 40, 50, 80, 100, 200, 400
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 815,275,773,400, is 1.
Now, the common factors can be found like this.
815:5x 163
275:5x 5x 11
773:773
400:2x 2x 2x 2x 5x 5
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5x 5x 5 = 125
Therefore, the value for common factors is 125.
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 = 69299450000/(1x125)
LCM = 69299450000/125
LCM = 554395600
Thus, we can understand that the LCM of 815,275,773,400 is 554395600.
