Given numbers are 658,754,812,812
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 658,754,812,812 is 496132.
Find LCM of 658,754,812,812 with Prime Factorization
| 2 | 658, 754, 812, 812 |
| 2 | 329, 377, 406, 406 |
| 7 | 329, 377, 203, 203 |
| 29 | 47, 377, 29, 29 |
| 47, 13, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 29 x 47 x 13 x 1 x 1 = 496132
Therefore, the lowest common multiple of 658,754,812,812 is 496132.
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.
658 x 754 x 812 x 812 = 327121657408
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.
658 : 1, 2, 7, 14, 47, 94, 329, 658
754 : 1, 2, 13, 26, 29, 58, 377, 754
812 : 1, 2, 4, 7, 14, 28, 29, 58, 116, 203, 406, 812
812 : 1, 2, 4, 7, 14, 28, 29, 58, 116, 203, 406, 812
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 658,754,812,812, is 2.
Now, the common factors can be found like this.
658:2x 7x 47
754:2x 13x 29
812:2x 2x 7x 29
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 2x 7x 7x 29x 29 = 329672
Therefore, the value for common factors is 329672.
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 = 327121657408/(2x329672)
LCM = 327121657408/659344
LCM = 496132
Thus, we can understand that the LCM of 658,754,812,812 is 496132.
