Given numbers are 6,812,638,427
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 6,812,638,427 is 1634556.
Find LCM of 6,812,638,427 with Prime Factorization
| 2 | 6, 812, 638, 427 |
| 7 | 3, 406, 319, 427 |
| 29 | 3, 58, 319, 61 |
| 3, 2, 11, 61 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 29 x 3 x 2 x 11 x 61 = 1634556
Therefore, the lowest common multiple of 6,812,638,427 is 1634556.
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.
6 x 812 x 638 x 427 = 1327259472
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.
6 : 1, 2, 3, 6
812 : 1, 2, 4, 7, 14, 28, 29, 58, 116, 203, 406, 812
638 : 1, 2, 11, 22, 29, 58, 319, 638
427 : 1, 7, 61, 427
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 6,812,638,427, is 1.
Now, the common factors can be found like this.
6:2x 3
812:2x 2x 7x 29
638:2x 11x 29
427:7x 61
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 7x 29 = 812
Therefore, the value for common factors is 812.
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 = 1327259472/(1x812)
LCM = 1327259472/812
LCM = 1634556
Thus, we can understand that the LCM of 6,812,638,427 is 1634556.
