Given numbers are 989,449,161,473,966
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 989,449,161,473,966 is 205156182.
Find LCM of 989,449,161,473,966 with Prime Factorization
7 | 989, 449, 161, 473, 966 |
23 | 989, 449, 23, 473, 138 |
43 | 43, 449, 1, 473, 6 |
1, 449, 1, 11, 6 |
Multiply the prime numbers at the bottom and the left side.
7 x 23 x 43 x 1 x 449 x 1 x 11 x 6 = 205156182
Therefore, the lowest common multiple of 989,449,161,473,966 is 205156182.
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 449 x 161 x 473 x 966 = 32666813703678
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
449 : 1, 449
161 : 1, 7, 23, 161
473 : 1, 11, 43, 473
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 989,449,161,473,966, is 1.
Now, the common factors can be found like this.
989:23x 43
449:449
161:7x 23
473:11x 43
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.
7x 23x 23x 43 = 159229
Therefore, the value for common factors is 159229.
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 = 32666813703678/(1x159229)
LCM = 32666813703678/159229
LCM = 205156182
Thus, we can understand that the LCM of 989,449,161,473,966 is 205156182.
