Given numbers are 978,361,709,665
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 978,361,709,665 is 8761134270.
Find LCM of 978,361,709,665 with Prime Factorization
19 | 978, 361, 709, 665 |
978, 19, 709, 35 |
Multiply the prime numbers at the bottom and the left side.
19 x 978 x 19 x 709 x 35 = 8761134270
Therefore, the lowest common multiple of 978,361,709,665 is 8761134270.
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.
978 x 361 x 709 x 665 = 166461551130
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.
978 : 1, 2, 3, 6, 163, 326, 489, 978
361 : 1, 19, 361
709 : 1, 709
665 : 1, 5, 7, 19, 35, 95, 133, 665
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 978,361,709,665, is 1.
Now, the common factors can be found like this.
978:2x 3x 163
361:19x 19
709:709
665:5x 7x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
19 = 19
Therefore, the value for common factors is 19.
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 = 166461551130/(1x19)
LCM = 166461551130/19
LCM = 8761134270
Thus, we can understand that the LCM of 978,361,709,665 is 8761134270.
