Calculate the LCM of 806,831,124,815

Given numbers are 806,831,124,815

The least common multiple of numbers can be find using the prime factorization method or LCM formula.

The LCM of 806,831,124,815 is 1091751180.

Find LCM of 806,831,124,815 with Prime Factorization


2 806, 831, 124, 815
31 403, 831, 62, 815
13, 831, 2, 815

Multiply the prime numbers at the bottom and the left side.

2 x 31 x 13 x 831 x 2 x 815 = 1091751180

Therefore, the lowest common multiple of 806,831,124,815 is 1091751180.

LCM Formula to Find Lowest Common Multiple of 806,831,124,815

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.

806 x 831 x 124 x 815 = 67688573160

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.

806 : 1, 2, 13, 26, 31, 62, 403, 806

831 : 1, 3, 277, 831

124 : 1, 2, 4, 31, 62, 124

815 : 1, 5, 163, 815

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 806,831,124,815, is 1.

Now, the common factors can be found like this.

806:2x 13x 31

831:3x 277

124:2x 2x 31

815:5x 163

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2x 31 = 62

Therefore, the value for common factors is 62.

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 = 67688573160/(1x62)

LCM = 67688573160/62

LCM = 1091751180

Thus, we can understand that the LCM of 806,831,124,815 is 1091751180.
