Given numbers are 803,721,618,668

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

The LCM of 803,721,618,668 is 1160241852.

Find LCM of 803,721,618,668 with Prime Factorization

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

2 x 103 x 803 x 7 x 3 x 334 = 1160241852

Therefore, the lowest common multiple of 803,721,618,668 is 1160241852.

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.

803 x 721 x 618 x 668 = 239009821512

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.

803 : 1, 11, 73, 803

721 : 1, 7, 103, 721

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

668 : 1, 2, 4, 167, 334, 668

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 803,721,618,668, is 1.

Now, the common factors can be found like this.

803:11x 73

721:7x 103

618:2x 3x 103

668:2x 2x 167

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 = 239009821512/(1x206)

LCM = 239009821512/206

LCM = 1160241852

Thus, we can understand that the LCM of 803,721,618,668 is 1160241852.
