The LCM of 765,340,651,615 is 27224820.

Find LCM of 765,340,651,615 with Prime Factorization


3 765, 340, 651, 615
5 255, 340, 217, 205
17 51, 68, 217, 41
3, 4, 217, 41

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

3 x 5 x 17 x 3 x 4 x 217 x 41 = 27224820

Therefore, the lowest common multiple of 765,340,651,615 is 27224820.

LCM Formula to Find Lowest Common Multiple of 765,340,651,615

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.

765 x 340 x 651 x 615 = 104134936500

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.

765 : 1, 3, 5, 9, 15, 17, 45, 51, 85, 153, 255, 765

340 : 1, 2, 4, 5, 10, 17, 20, 34, 68, 85, 170, 340

651 : 1, 3, 7, 21, 31, 93, 217, 651

615 : 1, 3, 5, 15, 41, 123, 205, 615

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 765,340,651,615, is 1.

Now, the common factors can be found like this.

765:3x 3x 5x 17

340:2x 2x 5x 17

651:3x 7x 31

615:3x 5x 41

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 5x 5x 17 = 3825

Therefore, the value for common factors is 3825.

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 = 104134936500/(1x3825)

LCM = 104134936500/3825

LCM = 27224820

Thus, we can understand that the LCM of 765,340,651,615 is 27224820.
