Given numbers are 646,213,242,757

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

The LCM of 646,213,242,757 is 12603564006.

Find LCM of 646,213,242,757 with Prime Factorization

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

2 x 323 x 213 x 121 x 757 = 12603564006

Therefore, the lowest common multiple of 646,213,242,757 is 12603564006.

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 213 x 242 x 757 = 25207128012

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

213 : 1, 3, 71, 213

242 : 1, 2, 11, 22, 121, 242

757 : 1, 757

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 646,213,242,757, is 1.

Now, the common factors can be found like this.

646:2x 17x 19

213:3x 71

242:2x 11x 11

757:757

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

2 = 2

Therefore, the value for common factors is 2.

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 = 25207128012/(1x2)

LCM = 25207128012/2

LCM = 12603564006

Thus, we can understand that the LCM of 646,213,242,757 is 12603564006.
