Given numbers are 654,872,638,678
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 654,872,638,678 is 94298952.
Find LCM of 654,872,638,678 with Prime Factorization
2 | 654, 872, 638, 678 |
3 | 327, 436, 319, 339 |
109 | 109, 436, 319, 113 |
1, 4, 319, 113 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 109 x 1 x 4 x 319 x 113 = 94298952
Therefore, the lowest common multiple of 654,872,638,678 is 94298952.
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.
654 x 872 x 638 x 678 = 246686058432
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.
654 : 1, 2, 3, 6, 109, 218, 327, 654
872 : 1, 2, 4, 8, 109, 218, 436, 872
638 : 1, 2, 11, 22, 29, 58, 319, 638
678 : 1, 2, 3, 6, 113, 226, 339, 678
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 654,872,638,678, is 2.
Now, the common factors can be found like this.
654:2x 3x 109
872:2x 2x 2x 109
638:2x 11x 29
678:2x 3x 113
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 3x 109 = 1308
Therefore, the value for common factors is 1308.
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 = 246686058432/(2x1308)
LCM = 246686058432/2616
LCM = 94298952
Thus, we can understand that the LCM of 654,872,638,678 is 94298952.
