Given numbers are 452,289,689,578,638
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 452,289,689,578,638 is 28710858748.
Find LCM of 452,289,689,578,638 with Prime Factorization
2 | 452, 289, 689, 578, 638 |
17 | 226, 289, 689, 289, 319 |
17 | 226, 17, 689, 17, 319 |
226, 1, 689, 1, 319 |
Multiply the prime numbers at the bottom and the left side.
2 x 17 x 17 x 226 x 1 x 689 x 1 x 319 = 28710858748
Therefore, the lowest common multiple of 452,289,689,578,638 is 28710858748.
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.
452 x 289 x 689 x 578 x 638 = 33189752712688
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.
452 : 1, 2, 4, 113, 226, 452
289 : 1, 17, 289
689 : 1, 13, 53, 689
578 : 1, 2, 17, 34, 289, 578
638 : 1, 2, 11, 22, 29, 58, 319, 638
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 452,289,689,578,638, is 1.
Now, the common factors can be found like this.
452:2x 2x 113
289:17x 17
689:13x 53
578:2x 17x 17
638:2x 11x 29
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 17x 17 = 1156
Therefore, the value for common factors is 1156.
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 = 33189752712688/(1x1156)
LCM = 33189752712688/1156
LCM = 28710858748
Thus, we can understand that the LCM of 452,289,689,578,638 is 28710858748.
