Given numbers are 981,974,129,190

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

The LCM of 981,974,129,190 is 3903192990.

Find LCM of 981,974,129,190 with Prime Factorization

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

2 x 3 x 327 x 487 x 43 x 95 = 3903192990

Therefore, the lowest common multiple of 981,974,129,190 is 3903192990.

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 974 x 129 x 190 = 23419157940

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

974 : 1, 2, 487, 974

129 : 1, 3, 43, 129

190 : 1, 2, 5, 10, 19, 38, 95, 190

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 981,974,129,190, is 1.

Now, the common factors can be found like this.

981:3x 3x 109

974:2x 487

129:3x 43

190:2x 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.

2x 3 = 6

Therefore, the value for common factors is 6.

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 = 23419157940/(1x6)

LCM = 23419157940/6

LCM = 3903192990

Thus, we can understand that the LCM of 981,974,129,190 is 3903192990.
