Given numbers are 665,406,841,867

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

The LCM of 665,406,841,867 is 969765510.

Find LCM of 665,406,841,867 with Prime Factorization

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

7 x 29 x 95 x 2 x 29 x 867 = 969765510

Therefore, the lowest common multiple of 665,406,841,867 is 969765510.

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.

665 x 406 x 841 x 867 = 196862398530

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.

665 : 1, 5, 7, 19, 35, 95, 133, 665

406 : 1, 2, 7, 14, 29, 58, 203, 406

841 : 1, 29, 841

867 : 1, 3, 17, 51, 289, 867

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 665,406,841,867, is 1.

Now, the common factors can be found like this.

665:5x 7x 19

406:2x 7x 29

841:29x 29

867:3x 17x 17

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

7x 29 = 203

Therefore, the value for common factors is 203.

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 = 196862398530/(1x203)

LCM = 196862398530/203

LCM = 969765510

Thus, we can understand that the LCM of 665,406,841,867 is 969765510.
