Given numbers are 986,160,641,866

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

The LCM of 986,160,641,866 is 21893380640.

Find LCM of 986,160,641,866 with Prime Factorization

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

2 x 493 x 80 x 641 x 433 = 21893380640

Therefore, the lowest common multiple of 986,160,641,866 is 21893380640.

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.

986 x 160 x 641 x 866 = 87573522560

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.

986 : 1, 2, 17, 29, 34, 58, 493, 986

160 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 80, 160

641 : 1, 641

866 : 1, 2, 433, 866

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 986,160,641,866, is 1.

Now, the common factors can be found like this.

986:2x 17x 29

160:2x 2x 2x 2x 2x 5

641:641

866:2x 433

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 87573522560/(1x4)

LCM = 87573522560/4

LCM = 21893380640

Thus, we can understand that the LCM of 986,160,641,866 is 21893380640.
