Given numbers are 457,766,575,390,812
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 457,766,575,390,812 is 3187156982100.
Find LCM of 457,766,575,390,812 with Prime Factorization
| 2 | 457, 766, 575, 390, 812 |
| 5 | 457, 383, 575, 195, 406 |
| 457, 383, 115, 39, 406 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 457 x 383 x 115 x 39 x 406 = 3187156982100
Therefore, the lowest common multiple of 457,766,575,390,812 is 3187156982100.
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.
457 x 766 x 575 x 390 x 812 = 63743139642000
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.
457 : 1, 457
766 : 1, 2, 383, 766
575 : 1, 5, 23, 25, 115, 575
390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390
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 457,766,575,390,812, is 1.
Now, the common factors can be found like this.
457:457
766:2x 383
575:5x 5x 23
390:2x 3x 5x 13
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 5 = 20
Therefore, the value for common factors is 20.
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 = 63743139642000/(1x20)
LCM = 63743139642000/20
LCM = 3187156982100
Thus, we can understand that the LCM of 457,766,575,390,812 is 3187156982100.
