Given numbers are 191,209,556,973

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

The LCM of 191,209,556,973 is 155364748.

Find LCM of 191,209,556,973 with Prime Factorization

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

139 x 191 x 209 x 4 x 7 = 155364748

Therefore, the lowest common multiple of 191,209,556,973 is 155364748.

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.

191 x 209 x 556 x 973 = 21595699972

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.

191 : 1, 191

209 : 1, 11, 19, 209

556 : 1, 2, 4, 139, 278, 556

973 : 1, 7, 139, 973

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 191,209,556,973, is 1.

Now, the common factors can be found like this.

191:191

209:11x 19

556:2x 2x 139

973:7x 139

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

139 = 139

Therefore, the value for common factors is 139.

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 = 21595699972/(1x139)

LCM = 21595699972/139

LCM = 155364748

Thus, we can understand that the LCM of 191,209,556,973 is 155364748.
