Given numbers are 905,669,181,84
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 905,669,181,84 is 16952460.
Find LCM of 905,669,181,84 with Prime Factorization
3 | 905, 669, 181, 84 |
181 | 905, 223, 181, 28 |
5, 223, 1, 28 |
Multiply the prime numbers at the bottom and the left side.
3 x 181 x 5 x 223 x 1 x 28 = 16952460
Therefore, the lowest common multiple of 905,669,181,84 is 16952460.
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.
905 x 669 x 181 x 84 = 9205185780
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.
905 : 1, 5, 181, 905
669 : 1, 3, 223, 669
181 : 1, 181
84 : 1, 2, 3, 4, 6, 7, 12, 14, 21, 28, 42, 84
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 905,669,181,84, is 1.
Now, the common factors can be found like this.
905:5x 181
669:3x 223
181:181
84:2x 2x 3x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 181 = 543
Therefore, the value for common factors is 543.
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 = 9205185780/(1x543)
LCM = 9205185780/543
LCM = 16952460
Thus, we can understand that the LCM of 905,669,181,84 is 16952460.
