Given numbers are 797,636,512,786
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 797,636,512,786 is 8499565056.
Find LCM of 797,636,512,786 with Prime Factorization
| 2 | 797, 636, 512, 786 |
| 2 | 797, 318, 256, 393 |
| 3 | 797, 159, 128, 393 |
| 797, 53, 128, 131 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 797 x 53 x 128 x 131 = 8499565056
Therefore, the lowest common multiple of 797,636,512,786 is 8499565056.
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.
797 x 636 x 512 x 786 = 203989561344
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.
797 : 1, 797
636 : 1, 2, 3, 4, 6, 12, 53, 106, 159, 212, 318, 636
512 : 1, 2, 4, 8, 16, 32, 64, 128, 256, 512
786 : 1, 2, 3, 6, 131, 262, 393, 786
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 797,636,512,786, is 1.
Now, the common factors can be found like this.
797:797
636:2x 2x 3x 53
512:2x 2x 2x 2x 2x 2x 2x 2x 2
786:2x 3x 131
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 2x 3 = 24
Therefore, the value for common factors is 24.
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 = 203989561344/(1x24)
LCM = 203989561344/24
LCM = 8499565056
Thus, we can understand that the LCM of 797,636,512,786 is 8499565056.
