Given numbers are 812,380,754,969
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 812,380,754,969 is 51143820.
Find LCM of 812,380,754,969 with Prime Factorization
| 2 | 812, 380, 754, 969 |
| 2 | 406, 190, 377, 969 |
| 19 | 203, 95, 377, 969 |
| 29 | 203, 5, 377, 51 |
| 7, 5, 13, 51 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 19 x 29 x 7 x 5 x 13 x 51 = 51143820
Therefore, the lowest common multiple of 812,380,754,969 is 51143820.
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.
812 x 380 x 754 x 969 = 225441958560
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.
812 : 1, 2, 4, 7, 14, 28, 29, 58, 116, 203, 406, 812
380 : 1, 2, 4, 5, 10, 19, 20, 38, 76, 95, 190, 380
754 : 1, 2, 13, 26, 29, 58, 377, 754
969 : 1, 3, 17, 19, 51, 57, 323, 969
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 812,380,754,969, is 1.
Now, the common factors can be found like this.
812:2x 2x 7x 29
380:2x 2x 5x 19
754:2x 13x 29
969:3x 17x 19
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 19x 29 = 4408
Therefore, the value for common factors is 4408.
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 = 225441958560/(1x4408)
LCM = 225441958560/4408
LCM = 51143820
Thus, we can understand that the LCM of 812,380,754,969 is 51143820.
