Given numbers are 305,247,532,905,451
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 305,247,532,905,451 is 172190798780.
Find LCM of 305,247,532,905,451 with Prime Factorization
5 | 305, 247, 532, 905, 451 |
19 | 61, 247, 532, 181, 451 |
61, 13, 28, 181, 451 |
Multiply the prime numbers at the bottom and the left side.
5 x 19 x 61 x 13 x 28 x 181 x 451 = 172190798780
Therefore, the lowest common multiple of 305,247,532,905,451 is 172190798780.
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.
305 x 247 x 532 x 905 x 451 = 16358125884100
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.
305 : 1, 5, 61, 305
247 : 1, 13, 19, 247
532 : 1, 2, 4, 7, 14, 19, 28, 38, 76, 133, 266, 532
905 : 1, 5, 181, 905
451 : 1, 11, 41, 451
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 305,247,532,905,451, is 1.
Now, the common factors can be found like this.
305:5x 61
247:13x 19
532:2x 2x 7x 19
905:5x 181
451:11x 41
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5x 19 = 95
Therefore, the value for common factors is 95.
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 = 16358125884100/(1x95)
LCM = 16358125884100/95
LCM = 172190798780
Thus, we can understand that the LCM of 305,247,532,905,451 is 172190798780.
