Calculate the LCM of 473,489,394,987,987

Given numbers are 473,489,394,987,987

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

The LCM of 473,489,394,987,987 is 29982104922.

Find LCM of 473,489,394,987,987 with Prime Factorization


3 473, 489, 394, 987, 987
7 473, 163, 394, 329, 329
47 473, 163, 394, 47, 47
473, 163, 394, 1, 1

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

3 x 7 x 47 x 473 x 163 x 394 x 1 x 1 = 29982104922

Therefore, the lowest common multiple of 473,489,394,987,987 is 29982104922.

LCM Formula to Find Lowest Common Multiple of 473,489,394,987,987

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.

473 x 489 x 394 x 987 x 987 = 88777012674042

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.

473 : 1, 11, 43, 473

489 : 1, 3, 163, 489

394 : 1, 2, 197, 394

987 : 1, 3, 7, 21, 47, 141, 329, 987

987 : 1, 3, 7, 21, 47, 141, 329, 987

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 473,489,394,987,987, is 1.

Now, the common factors can be found like this.

473:11x 43

489:3x 163

394:2x 197

987:3x 7x 47

987:3x 7x 47

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 7x 47 = 2961

Therefore, the value for common factors is 2961.

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 = 88777012674042/(1x2961)

LCM = 88777012674042/2961

LCM = 29982104922

Thus, we can understand that the LCM of 473,489,394,987,987 is 29982104922.
