Given numbers are 728,789,982,628

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

The LCM of 728,789,982,628 is 44278156104.

Find LCM of 728,789,982,628 with Prime Factorization


2 728, 789, 982, 628
2 364, 789, 491, 314
182, 789, 491, 157

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

2 x 2 x 182 x 789 x 491 x 157 = 44278156104

Therefore, the lowest common multiple of 728,789,982,628 is 44278156104.

LCM Formula to Find Lowest Common Multiple of 728,789,982,628

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 789 x 982 x 628 = 354225248832

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

789 : 1, 3, 263, 789

982 : 1, 2, 491, 982

628 : 1, 2, 4, 157, 314, 628

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 728,789,982,628, is 1.

Now, the common factors can be found like this.

728:2x 2x 2x 7x 13

789:3x 263

982:2x 491

628:2x 2x 157

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 = 354225248832/(1x8)

LCM = 354225248832/8

LCM = 44278156104

Thus, we can understand that the LCM of 728,789,982,628 is 44278156104.
