Given numbers are 831,136,238,991

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

The LCM of 831,136,238,991 is 783991992.

Find LCM of 831,136,238,991 with Prime Factorization

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

2 x 17 x 831 x 4 x 7 x 991 = 783991992

Therefore, the lowest common multiple of 831,136,238,991 is 783991992.

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.

831 x 136 x 238 x 991 = 26655727728

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.

831 : 1, 3, 277, 831

136 : 1, 2, 4, 8, 17, 34, 68, 136

238 : 1, 2, 7, 14, 17, 34, 119, 238

991 : 1, 991

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 831,136,238,991, is 1.

Now, the common factors can be found like this.

831:3x 277

136:2x 2x 2x 17

238:2x 7x 17

991:991

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

2x 17 = 34

Therefore, the value for common factors is 34.

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 = 26655727728/(1x34)

LCM = 26655727728/34

LCM = 783991992

Thus, we can understand that the LCM of 831,136,238,991 is 783991992.
