Given numbers are 654,981,969,115

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

The LCM of 654,981,969,115 is 72878490.

Find LCM of 654,981,969,115 with Prime Factorization

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

3 x 109 x 2 x 3 x 323 x 115 = 72878490

Therefore, the lowest common multiple of 654,981,969,115 is 72878490.

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.

654 x 981 x 969 x 115 = 71493798690

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.

654 : 1, 2, 3, 6, 109, 218, 327, 654

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

969 : 1, 3, 17, 19, 51, 57, 323, 969

115 : 1, 5, 23, 115

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 654,981,969,115, is 1.

Now, the common factors can be found like this.

654:2x 3x 109

981:3x 3x 109

969:3x 17x 19

115:5x 23

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

3x 3x 109 = 981

Therefore, the value for common factors is 981.

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 = 71493798690/(1x981)

LCM = 71493798690/981

LCM = 72878490

Thus, we can understand that the LCM of 654,981,969,115 is 72878490.
