Given numbers are 905,982,130,686
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 905,982,130,686 is 3962757890.
Find LCM of 905,982,130,686 with Prime Factorization
2 | 905, 982, 130, 686 |
5 | 905, 491, 65, 343 |
181, 491, 13, 343 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 181 x 491 x 13 x 343 = 3962757890
Therefore, the lowest common multiple of 905,982,130,686 is 3962757890.
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 982 x 130 x 686 = 79255157800
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
982 : 1, 2, 491, 982
130 : 1, 2, 5, 10, 13, 26, 65, 130
686 : 1, 2, 7, 14, 49, 98, 343, 686
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 905,982,130,686, is 1.
Now, the common factors can be found like this.
905:5x 181
982:2x 491
130:2x 5x 13
686:2x 7x 7x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 5 = 20
Therefore, the value for common factors is 20.
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 = 79255157800/(1x20)
LCM = 79255157800/20
LCM = 3962757890
Thus, we can understand that the LCM of 905,982,130,686 is 3962757890.
