Given numbers are 431,862,573,493
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 431,862,573,493 is 243505518.
Find LCM of 431,862,573,493 with Prime Factorization
| 431 | 431, 862, 573, 493 |
| 1, 2, 573, 493 |
Multiply the prime numbers at the bottom and the left side.
431 x 1 x 2 x 573 x 493 = 243505518
Therefore, the lowest common multiple of 431,862,573,493 is 243505518.
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.
431 x 862 x 573 x 493 = 104950878258
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.
431 : 1, 431
862 : 1, 2, 431, 862
573 : 1, 3, 191, 573
493 : 1, 17, 29, 493
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 431,862,573,493, is 1.
Now, the common factors can be found like this.
431:431
862:2x 431
573:3x 191
493:17x 29
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
431 = 431
Therefore, the value for common factors is 431.
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 = 104950878258/(1x431)
LCM = 104950878258/431
LCM = 243505518
Thus, we can understand that the LCM of 431,862,573,493 is 243505518.
