Calculate the LCM of 322,981,609,649

Given numbers are 322,981,609,649

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

The LCM of 322,981,609,649 is 5945215122.

Find LCM of 322,981,609,649 with Prime Factorization


3 322, 981, 609, 649
7 322, 327, 203, 649
46, 327, 29, 649

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

3 x 7 x 46 x 327 x 29 x 649 = 5945215122

Therefore, the lowest common multiple of 322,981,609,649 is 5945215122.

LCM Formula to Find Lowest Common Multiple of 322,981,609,649

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.

322 x 981 x 609 x 649 = 124849517562

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.

322 : 1, 2, 7, 14, 23, 46, 161, 322

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

609 : 1, 3, 7, 21, 29, 87, 203, 609

649 : 1, 11, 59, 649

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 322,981,609,649, is 1.

Now, the common factors can be found like this.

322:2x 7x 23

981:3x 3x 109

609:3x 7x 29

649:11x 59

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

3x 7 = 21

Therefore, the value for common factors is 21.

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 = 124849517562/(1x21)

LCM = 124849517562/21

LCM = 5945215122

Thus, we can understand that the LCM of 322,981,609,649 is 5945215122.
