Given numbers are 431,194,801,862,221
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 431,194,801,862,221 is 14801433894.
Find LCM of 431,194,801,862,221 with Prime Factorization
| 2 | 431, 194, 801, 862, 221 |
| 431 | 431, 97, 801, 431, 221 |
| 1, 97, 801, 1, 221 |
Multiply the prime numbers at the bottom and the left side.
2 x 431 x 1 x 97 x 801 x 1 x 221 = 14801433894
Therefore, the lowest common multiple of 431,194,801,862,221 is 14801433894.
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 194 x 801 x 862 x 221 = 12758836016628
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
194 : 1, 2, 97, 194
801 : 1, 3, 9, 89, 267, 801
862 : 1, 2, 431, 862
221 : 1, 13, 17, 221
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 431,194,801,862,221, is 1.
Now, the common factors can be found like this.
431:431
194:2x 97
801:3x 3x 89
862:2x 431
221:13x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 431 = 862
Therefore, the value for common factors is 862.
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 = 12758836016628/(1x862)
LCM = 12758836016628/862
LCM = 14801433894
Thus, we can understand that the LCM of 431,194,801,862,221 is 14801433894.
