Given numbers are 778,800,954,221,974

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

The LCM of 778,800,954,221,974 is 15976410184800.

Find LCM of 778,800,954,221,974 with Prime Factorization

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

2 x 389 x 400 x 477 x 221 x 487 = 15976410184800

Therefore, the lowest common multiple of 778,800,954,221,974 is 15976410184800.

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.

778 x 800 x 954 x 221 x 974 = 127811281478400

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.

778 : 1, 2, 389, 778

800 : 1, 2, 4, 5, 8, 10, 16, 20, 25, 32, 40, 50, 80, 100, 160, 200, 400, 800

954 : 1, 2, 3, 6, 9, 18, 53, 106, 159, 318, 477, 954

221 : 1, 13, 17, 221

974 : 1, 2, 487, 974

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 778,800,954,221,974, is 1.

Now, the common factors can be found like this.

778:2x 389

800:2x 2x 2x 2x 2x 5x 5

954:2x 3x 3x 53

221:13x 17

974:2x 487

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

2x 2x 2 = 8

Therefore, the value for common factors is 8.

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 = 127811281478400/(1x8)

LCM = 127811281478400/8

LCM = 15976410184800

Thus, we can understand that the LCM of 778,800,954,221,974 is 15976410184800.
