Given numbers are 945,821,223,698,878

The least common multiple of numbers can be find using the prime factorization method or LCM formula.

The LCM of 945,821,223,698,878 is 53015122779570.

Find LCM of 945,821,223,698,878 with Prime Factorization

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

2 x 945 x 821 x 223 x 349 x 439 = 53015122779570

Therefore, the lowest common multiple of 945,821,223,698,878 is 53015122779570.

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.

945 x 821 x 223 x 698 x 878 = 106030245559140

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.

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

821 : 1, 821

223 : 1, 223

698 : 1, 2, 349, 698

878 : 1, 2, 439, 878

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 945,821,223,698,878, is 1.

Now, the common factors can be found like this.

945:3x 3x 3x 5x 7

821:821

223:223

698:2x 349

878:2x 439

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

2 = 2

Therefore, the value for common factors is 2.

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 = 106030245559140/(1x2)

LCM = 106030245559140/2

LCM = 53015122779570

Thus, we can understand that the LCM of 945,821,223,698,878 is 53015122779570.
