Given numbers are 804,911,860,971
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 804,911,860,971 is 152908671660.
Find LCM of 804,911,860,971 with Prime Factorization
| 2 | 804, 911, 860, 971 |
| 2 | 402, 911, 430, 971 |
| 201, 911, 215, 971 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 201 x 911 x 215 x 971 = 152908671660
Therefore, the lowest common multiple of 804,911,860,971 is 152908671660.
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.
804 x 911 x 860 x 971 = 611634686640
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.
804 : 1, 2, 3, 4, 6, 12, 67, 134, 201, 268, 402, 804
911 : 1, 911
860 : 1, 2, 4, 5, 10, 20, 43, 86, 172, 215, 430, 860
971 : 1, 971
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 804,911,860,971, is 1.
Now, the common factors can be found like this.
804:2x 2x 3x 67
911:911
860:2x 2x 5x 43
971:971
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2 = 4
Therefore, the value for common factors is 4.
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 = 611634686640/(1x4)
LCM = 611634686640/4
LCM = 152908671660
Thus, we can understand that the LCM of 804,911,860,971 is 152908671660.
