Given numbers are 536,390,911,871
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 536,390,911,871 is 95217720.
Find LCM of 536,390,911,871 with Prime Factorization
| 2 | 536, 390, 911, 871 |
| 13 | 268, 195, 911, 871 |
| 67 | 268, 15, 911, 67 |
| 4, 15, 911, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 13 x 67 x 4 x 15 x 911 x 1 = 95217720
Therefore, the lowest common multiple of 536,390,911,871 is 95217720.
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.
536 x 390 x 911 x 871 = 165869268240
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.
536 : 1, 2, 4, 8, 67, 134, 268, 536
390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390
911 : 1, 911
871 : 1, 13, 67, 871
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 536,390,911,871, is 1.
Now, the common factors can be found like this.
536:2x 2x 2x 67
390:2x 3x 5x 13
911:911
871:13x 67
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 13x 67 = 1742
Therefore, the value for common factors is 1742.
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 = 165869268240/(1x1742)
LCM = 165869268240/1742
LCM = 95217720
Thus, we can understand that the LCM of 536,390,911,871 is 95217720.
