Given numbers are 909,254,871,280
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 909,254,871,280 is 28154238840.
Find LCM of 909,254,871,280 with Prime Factorization
| 2 | 909, 254, 871, 280 |
| 909, 127, 871, 140 |
Multiply the prime numbers at the bottom and the left side.
2 x 909 x 127 x 871 x 140 = 28154238840
Therefore, the lowest common multiple of 909,254,871,280 is 28154238840.
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.
909 x 254 x 871 x 280 = 56308477680
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.
909 : 1, 3, 9, 101, 303, 909
254 : 1, 2, 127, 254
871 : 1, 13, 67, 871
280 : 1, 2, 4, 5, 7, 8, 10, 14, 20, 28, 35, 40, 56, 70, 140, 280
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 909,254,871,280, is 1.
Now, the common factors can be found like this.
909:3x 3x 101
254:2x 127
871:13x 67
280:2x 2x 2x 5x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2 = 2
Therefore, the value for common factors is 2.
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 = 56308477680/(1x2)
LCM = 56308477680/2
LCM = 28154238840
Thus, we can understand that the LCM of 909,254,871,280 is 28154238840.
