Given numbers are 827,421,712,686
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 827,421,712,686 is 85027952072.
Find LCM of 827,421,712,686 with Prime Factorization
2 | 827, 421, 712, 686 |
827, 421, 356, 343 |
Multiply the prime numbers at the bottom and the left side.
2 x 827 x 421 x 356 x 343 = 85027952072
Therefore, the lowest common multiple of 827,421,712,686 is 85027952072.
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.
827 x 421 x 712 x 686 = 170055904144
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.
827 : 1, 827
421 : 1, 421
712 : 1, 2, 4, 8, 89, 178, 356, 712
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 827,421,712,686, is 1.
Now, the common factors can be found like this.
827:827
421:421
712:2x 2x 2x 89
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.
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 = 170055904144/(1x2)
LCM = 170055904144/2
LCM = 85027952072
Thus, we can understand that the LCM of 827,421,712,686 is 85027952072.
