Given numbers are 821,206,673,618

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

The LCM of 821,206,673,618 is 341465394.

Find LCM of 821,206,673,618 with Prime Factorization

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

2 x 103 x 821 x 1 x 673 x 3 = 341465394

Therefore, the lowest common multiple of 821,206,673,618 is 341465394.

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.

821 x 206 x 673 x 618 = 70341871164

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.

821 : 1, 821

206 : 1, 2, 103, 206

673 : 1, 673

618 : 1, 2, 3, 6, 103, 206, 309, 618

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 821,206,673,618, is 1.

Now, the common factors can be found like this.

821:821

206:2x 103

673:673

618:2x 3x 103

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

2x 103 = 206

Therefore, the value for common factors is 206.

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 = 70341871164/(1x206)

LCM = 70341871164/206

LCM = 341465394

Thus, we can understand that the LCM of 821,206,673,618 is 341465394.
