Given numbers are 473,573,418,693
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 473,573,418,693 is 216281142.
Find LCM of 473,573,418,693 with Prime Factorization
| 3 | 473, 573, 418, 693 |
| 11 | 473, 191, 418, 231 |
| 43, 191, 38, 21 |
Multiply the prime numbers at the bottom and the left side.
3 x 11 x 43 x 191 x 38 x 21 = 216281142
Therefore, the lowest common multiple of 473,573,418,693 is 216281142.
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.
473 x 573 x 418 x 693 = 78510054546
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.
473 : 1, 11, 43, 473
573 : 1, 3, 191, 573
418 : 1, 2, 11, 19, 22, 38, 209, 418
693 : 1, 3, 7, 9, 11, 21, 33, 63, 77, 99, 231, 693
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 473,573,418,693, is 1.
Now, the common factors can be found like this.
473:11x 43
573:3x 191
418:2x 11x 19
693:3x 3x 7x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 11x 11 = 363
Therefore, the value for common factors is 363.
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 = 78510054546/(1x363)
LCM = 78510054546/363
LCM = 216281142
Thus, we can understand that the LCM of 473,573,418,693 is 216281142.
