The LCM of 225,378,509,765 is 81770850.

Find LCM of 225,378,509,765 with Prime Factorization


3 225, 378, 509, 765
3 75, 126, 509, 255
5 25, 42, 509, 85
5, 42, 509, 17

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

3 x 3 x 5 x 5 x 42 x 509 x 17 = 81770850

Therefore, the lowest common multiple of 225,378,509,765 is 81770850.

LCM Formula to Find Lowest Common Multiple of 225,378,509,765

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.

225 x 378 x 509 x 765 = 33117194250

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.

225 : 1, 3, 5, 9, 15, 25, 45, 75, 225

378 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 27, 42, 54, 63, 126, 189, 378

509 : 1, 509

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 225,378,509,765, is 1.

Now, the common factors can be found like this.

225:3x 3x 5x 5

378:2x 3x 3x 3x 7

509:509

765:3x 3x 5x 17

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 3x 3x 5 = 405

Therefore, the value for common factors is 405.

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 = 33117194250/(1x405)

LCM = 33117194250/405

LCM = 81770850

Thus, we can understand that the LCM of 225,378,509,765 is 81770850.
