The LCM of 705,429,754,309 is 602268810.

Find LCM of 705,429,754,309 with Prime Factorization


3 705, 429, 754, 309
13 235, 143, 754, 103
235, 11, 58, 103

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

3 x 13 x 235 x 11 x 58 x 103 = 602268810

Therefore, the lowest common multiple of 705,429,754,309 is 602268810.

LCM Formula to Find Lowest Common Multiple of 705,429,754,309

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.

705 x 429 x 754 x 309 = 70465450770

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.

705 : 1, 3, 5, 15, 47, 141, 235, 705

429 : 1, 3, 11, 13, 33, 39, 143, 429

754 : 1, 2, 13, 26, 29, 58, 377, 754

309 : 1, 3, 103, 309

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 705,429,754,309, is 1.

Now, the common factors can be found like this.

705:3x 5x 47

429:3x 11x 13

754:2x 13x 29

309:3x 103

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 13 = 117

Therefore, the value for common factors is 117.

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 = 70465450770/(1x117)

LCM = 70465450770/117

LCM = 602268810

Thus, we can understand that the LCM of 705,429,754,309 is 602268810.
