The LCM of 609,798,817,945 is 44779770.

Find LCM of 609,798,817,945 with Prime Factorization


3 609, 798, 817, 945
7 203, 266, 817, 315
19 29, 38, 817, 45
29, 2, 43, 45

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

3 x 7 x 19 x 29 x 2 x 43 x 45 = 44779770

Therefore, the lowest common multiple of 609,798,817,945 is 44779770.

LCM Formula to Find Lowest Common Multiple of 609,798,817,945

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.

609 x 798 x 817 x 945 = 375209692830

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.

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

798 : 1, 2, 3, 6, 7, 14, 19, 21, 38, 42, 57, 114, 133, 266, 399, 798

817 : 1, 19, 43, 817

945 : 1, 3, 5, 7, 9, 15, 21, 27, 35, 45, 63, 105, 135, 189, 315, 945

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 609,798,817,945, is 1.

Now, the common factors can be found like this.

609:3x 7x 29

798:2x 3x 7x 19

817:19x 43

945:3x 3x 3x 5x 7

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 7x 19 = 8379

Therefore, the value for common factors is 8379.

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 = 375209692830/(1x8379)

LCM = 375209692830/8379

LCM = 44779770

Thus, we can understand that the LCM of 609,798,817,945 is 44779770.
