Given numbers are 646,713,374,381

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

The LCM of 646,713,374,381 is 1930366218.

Find LCM of 646,713,374,381 with Prime Factorization

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

2 x 17 x 19 x 713 x 11 x 381 = 1930366218

Therefore, the lowest common multiple of 646,713,374,381 is 1930366218.

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 713 x 374 x 381 = 65632451412

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

713 : 1, 23, 31, 713

374 : 1, 2, 11, 17, 22, 34, 187, 374

381 : 1, 3, 127, 381

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 646,713,374,381, is 1.

Now, the common factors can be found like this.

646:2x 17x 19

713:23x 31

374:2x 11x 17

381:3x 127

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 = 65632451412/(1x34)

LCM = 65632451412/34

LCM = 1930366218

Thus, we can understand that the LCM of 646,713,374,381 is 1930366218.
