Given numbers are 638,829,747,222,812
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 638,829,747,222,812 is 204656513292.
Find LCM of 638,829,747,222,812 with Prime Factorization
| 2 | 638, 829, 747, 222, 812 |
| 3 | 319, 829, 747, 111, 406 |
| 29 | 319, 829, 249, 37, 406 |
| 11, 829, 249, 37, 14 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 29 x 11 x 829 x 249 x 37 x 14 = 204656513292
Therefore, the lowest common multiple of 638,829,747,222,812 is 204656513292.
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.
638 x 829 x 747 x 222 x 812 = 71220466625616
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.
638 : 1, 2, 11, 22, 29, 58, 319, 638
829 : 1, 829
747 : 1, 3, 9, 83, 249, 747
222 : 1, 2, 3, 6, 37, 74, 111, 222
812 : 1, 2, 4, 7, 14, 28, 29, 58, 116, 203, 406, 812
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 638,829,747,222,812, is 1.
Now, the common factors can be found like this.
638:2x 11x 29
829:829
747:3x 3x 83
222:2x 3x 37
812:2x 2x 7x 29
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 3x 29 = 348
Therefore, the value for common factors is 348.
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 = 71220466625616/(1x348)
LCM = 71220466625616/348
LCM = 204656513292
Thus, we can understand that the LCM of 638,829,747,222,812 is 204656513292.
