Given numbers are 989,616,998,661
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 989,616,998,661 is 200945834936.
Find LCM of 989,616,998,661 with Prime Factorization
2 | 989, 616, 998, 661 |
989, 308, 499, 661 |
Multiply the prime numbers at the bottom and the left side.
2 x 989 x 308 x 499 x 661 = 200945834936
Therefore, the lowest common multiple of 989,616,998,661 is 200945834936.
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 616 x 998 x 661 = 401891669872
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
616 : 1, 2, 4, 7, 8, 11, 14, 22, 28, 44, 56, 77, 88, 154, 308, 616
998 : 1, 2, 499, 998
661 : 1, 661
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 989,616,998,661, is 1.
Now, the common factors can be found like this.
989:23x 43
616:2x 2x 2x 7x 11
998:2x 499
661:661
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2 = 2
Therefore, the value for common factors is 2.
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 = 401891669872/(1x2)
LCM = 401891669872/2
LCM = 200945834936
Thus, we can understand that the LCM of 989,616,998,661 is 200945834936.
