Given numbers are 845,421,421,494,221
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 845,421,421,494,221 is 229811270.
Find LCM of 845,421,421,494,221 with Prime Factorization
13 | 845, 421, 421, 494, 221 |
421 | 65, 421, 421, 38, 17 |
65, 1, 1, 38, 17 |
Multiply the prime numbers at the bottom and the left side.
13 x 421 x 65 x 1 x 1 x 38 x 17 = 229811270
Therefore, the lowest common multiple of 845,421,421,494,221 is 229811270.
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.
845 x 421 x 421 x 494 x 221 = 16350842049230
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.
845 : 1, 5, 13, 65, 169, 845
421 : 1, 421
421 : 1, 421
494 : 1, 2, 13, 19, 26, 38, 247, 494
221 : 1, 13, 17, 221
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 845,421,421,494,221, is 1.
Now, the common factors can be found like this.
845:5x 13x 13
421:421
421:421
494:2x 13x 19
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.
13x 13x 421 = 71149
Therefore, the value for common factors is 71149.
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 = 16350842049230/(1x71149)
LCM = 16350842049230/71149
LCM = 229811270
Thus, we can understand that the LCM of 845,421,421,494,221 is 229811270.
