Given numbers are 989,685,643,966
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 989,685,643,966 is 18295619790.
Find LCM of 989,685,643,966 with Prime Factorization
23 | 989, 685, 643, 966 |
43, 685, 643, 42 |
Multiply the prime numbers at the bottom and the left side.
23 x 43 x 685 x 643 x 42 = 18295619790
Therefore, the lowest common multiple of 989,685,643,966 is 18295619790.
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.
989 x 685 x 643 x 966 = 420799255170
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.
989 : 1, 23, 43, 989
685 : 1, 5, 137, 685
643 : 1, 643
966 : 1, 2, 3, 6, 7, 14, 21, 23, 42, 46, 69, 138, 161, 322, 483, 966
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 989,685,643,966, is 1.
Now, the common factors can be found like this.
989:23x 43
685:5x 137
643:643
966:2x 3x 7x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
23 = 23
Therefore, the value for common factors is 23.
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 = 420799255170/(1x23)
LCM = 420799255170/23
LCM = 18295619790
Thus, we can understand that the LCM of 989,685,643,966 is 18295619790.
