Given numbers are 185,638,555,487
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 185,638,555,487 is 172441830.
Find LCM of 185,638,555,487 with Prime Factorization
5 | 185, 638, 555, 487 |
37 | 37, 638, 111, 487 |
1, 638, 3, 487 |
Multiply the prime numbers at the bottom and the left side.
5 x 37 x 1 x 638 x 3 x 487 = 172441830
Therefore, the lowest common multiple of 185,638,555,487 is 172441830.
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.
185 x 638 x 555 x 487 = 31901738550
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.
185 : 1, 5, 37, 185
638 : 1, 2, 11, 22, 29, 58, 319, 638
555 : 1, 3, 5, 15, 37, 111, 185, 555
487 : 1, 487
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 185,638,555,487, is 1.
Now, the common factors can be found like this.
185:5x 37
638:2x 11x 29
555:3x 5x 37
487:487
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5x 37 = 185
Therefore, the value for common factors is 185.
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 = 31901738550/(1x185)
LCM = 31901738550/185
LCM = 172441830
Thus, we can understand that the LCM of 185,638,555,487 is 172441830.
