Given numbers are 981,283,154,380

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

The LCM of 981,283,154,380 is 8123248980.

Find LCM of 981,283,154,380 with Prime Factorization

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

2 x 981 x 283 x 77 x 190 = 8123248980

Therefore, the lowest common multiple of 981,283,154,380 is 8123248980.

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.

981 x 283 x 154 x 380 = 16246497960

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.

981 : 1, 3, 9, 109, 327, 981

283 : 1, 283

154 : 1, 2, 7, 11, 14, 22, 77, 154

380 : 1, 2, 4, 5, 10, 19, 20, 38, 76, 95, 190, 380

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 981,283,154,380, is 1.

Now, the common factors can be found like this.

981:3x 3x 109

283:283

154:2x 7x 11

380:2x 2x 5x 19

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 = 16246497960/(1x2)

LCM = 16246497960/2

LCM = 8123248980

Thus, we can understand that the LCM of 981,283,154,380 is 8123248980.
