Given numbers are 728,673,778,950

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

The LCM of 728,673,778,950 is 90529402600.

Find LCM of 728,673,778,950 with Prime Factorization

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

2 x 364 x 673 x 389 x 475 = 90529402600

Therefore, the lowest common multiple of 728,673,778,950 is 90529402600.

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.

728 x 673 x 778 x 950 = 362117610400

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.

728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728

673 : 1, 673

778 : 1, 2, 389, 778

950 : 1, 2, 5, 10, 19, 25, 38, 50, 95, 190, 475, 950

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 728,673,778,950, is 1.

Now, the common factors can be found like this.

728:2x 2x 2x 7x 13

673:673

778:2x 389

950:2x 5x 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 2 = 4

Therefore, the value for common factors is 4.

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 = 362117610400/(1x4)

LCM = 362117610400/4

LCM = 90529402600

Thus, we can understand that the LCM of 728,673,778,950 is 90529402600.
