Given numbers are 977,871,784,108
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 977,871,784,108 is 18013269456.
Find LCM of 977,871,784,108 with Prime Factorization
| 2 | 977, 871, 784, 108 |
| 2 | 977, 871, 392, 54 |
| 977, 871, 196, 27 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 977 x 871 x 196 x 27 = 18013269456
Therefore, the lowest common multiple of 977,871,784,108 is 18013269456.
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.
977 x 871 x 784 x 108 = 72053077824
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.
977 : 1, 977
871 : 1, 13, 67, 871
784 : 1, 2, 4, 7, 8, 14, 16, 28, 49, 56, 98, 112, 196, 392, 784
108 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 108
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 977,871,784,108, is 1.
Now, the common factors can be found like this.
977:977
871:13x 67
784:2x 2x 2x 2x 7x 7
108:2x 2x 3x 3x 3
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 = 72053077824/(1x4)
LCM = 72053077824/4
LCM = 18013269456
Thus, we can understand that the LCM of 977,871,784,108 is 18013269456.
