Given numbers are 991,193,386,139

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

The LCM of 991,193,386,139 is 53171114.

Find LCM of 991,193,386,139 with Prime Factorization

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

193 x 991 x 1 x 2 x 139 = 53171114

Therefore, the lowest common multiple of 991,193,386,139 is 53171114.

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.

991 x 193 x 386 x 139 = 10262025002

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.

991 : 1, 991

193 : 1, 193

386 : 1, 2, 193, 386

139 : 1, 139

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 991,193,386,139, is 1.

Now, the common factors can be found like this.

991:991

193:193

386:2x 193

139:139

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

193 = 193

Therefore, the value for common factors is 193.

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 = 10262025002/(1x193)

LCM = 10262025002/193

LCM = 53171114

Thus, we can understand that the LCM of 991,193,386,139 is 53171114.
