Find LCM of 857,945,702,380 with Prime Factorization


2 857, 945, 702, 380
3 857, 945, 351, 190
3 857, 315, 117, 190
3 857, 105, 39, 190
5 857, 35, 13, 190
857, 7, 13, 38

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

2 x 3 x 3 x 3 x 5 x 857 x 7 x 13 x 38 = 800146620

Therefore, the lowest common multiple of 857,945,702,380 is 800146620.

LCM Formula to Find Lowest Common Multiple of 857,945,702,380

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.

857 x 945 x 702 x 380 = 216039587400

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.

857 : 1, 857

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

702 : 1, 2, 3, 6, 9, 13, 18, 26, 27, 39, 54, 78, 117, 234, 351, 702

380 : 1, 2, 4, 5, 10, 19, 20, 38, 76, 95, 190, 380

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 857,945,702,380, is 1.

Now, the common factors can be found like this.

857:857

945:3x 3x 3x 5x 7

702:2x 3x 3x 3x 13

380:2x 2x 5x 19

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

2x 3x 3x 3x 5 = 270

Therefore, the value for common factors is 270.

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 = 216039587400/(1x270)

LCM = 216039587400/270

LCM = 800146620

Thus, we can understand that the LCM of 857,945,702,380 is 800146620.
