Given numbers are 671,407,978,743
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 671,407,978,743 is 18040638858.
Find LCM of 671,407,978,743 with Prime Factorization
| 11 | 671, 407, 978, 743 |
| 61, 37, 978, 743 |
Multiply the prime numbers at the bottom and the left side.
11 x 61 x 37 x 978 x 743 = 18040638858
Therefore, the lowest common multiple of 671,407,978,743 is 18040638858.
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.
671 x 407 x 978 x 743 = 198447027438
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.
671 : 1, 11, 61, 671
407 : 1, 11, 37, 407
978 : 1, 2, 3, 6, 163, 326, 489, 978
743 : 1, 743
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 671,407,978,743, is 1.
Now, the common factors can be found like this.
671:11x 61
407:11x 37
978:2x 3x 163
743:743
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
11 = 11
Therefore, the value for common factors is 11.
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 = 198447027438/(1x11)
LCM = 198447027438/11
LCM = 18040638858
Thus, we can understand that the LCM of 671,407,978,743 is 18040638858.
