Given numbers are 919,969,505,221
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 919,969,505,221 is 5846204715.
Find LCM of 919,969,505,221 with Prime Factorization
17 | 919, 969, 505, 221 |
919, 57, 505, 13 |
Multiply the prime numbers at the bottom and the left side.
17 x 919 x 57 x 505 x 13 = 5846204715
Therefore, the lowest common multiple of 919,969,505,221 is 5846204715.
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.
919 x 969 x 505 x 221 = 99385480155
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.
919 : 1, 919
969 : 1, 3, 17, 19, 51, 57, 323, 969
505 : 1, 5, 101, 505
221 : 1, 13, 17, 221
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 919,969,505,221, is 1.
Now, the common factors can be found like this.
919:919
969:3x 17x 19
505:5x 101
221:13x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
17 = 17
Therefore, the value for common factors is 17.
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 = 99385480155/(1x17)
LCM = 99385480155/17
LCM = 5846204715
Thus, we can understand that the LCM of 919,969,505,221 is 5846204715.
