Given numbers are 646,177,442,377

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

The LCM of 646,177,442,377 is 43106934.

Find LCM of 646,177,442,377 with Prime Factorization

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

2 x 13 x 17 x 19 x 177 x 1 x 29 = 43106934

Therefore, the lowest common multiple of 646,177,442,377 is 43106934.

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.

646 x 177 x 442 x 377 = 19053264828

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.

646 : 1, 2, 17, 19, 34, 38, 323, 646

177 : 1, 3, 59, 177

442 : 1, 2, 13, 17, 26, 34, 221, 442

377 : 1, 13, 29, 377

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 646,177,442,377, is 1.

Now, the common factors can be found like this.

646:2x 17x 19

177:3x 59

442:2x 13x 17

377:13x 29

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

2x 13x 17 = 442

Therefore, the value for common factors is 442.

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 = 19053264828/(1x442)

LCM = 19053264828/442

LCM = 43106934

Thus, we can understand that the LCM of 646,177,442,377 is 43106934.
