Calculate the LCM of 728,205,494,889

Given numbers are 728,205,494,889

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

The LCM of 728,205,494,889 is 360116120.

Find LCM of 728,205,494,889 with Prime Factorization


2 728, 205, 494, 889
7 364, 205, 247, 889
13 52, 205, 247, 127
4, 205, 19, 127

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

2 x 7 x 13 x 4 x 205 x 19 x 127 = 360116120

Therefore, the lowest common multiple of 728,205,494,889 is 360116120.

LCM Formula to Find Lowest Common Multiple of 728,205,494,889

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 205 x 494 x 889 = 65541133840

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

205 : 1, 5, 41, 205

494 : 1, 2, 13, 19, 26, 38, 247, 494

889 : 1, 7, 127, 889

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 728,205,494,889, is 1.

Now, the common factors can be found like this.

728:2x 2x 2x 7x 13

205:5x 41

494:2x 13x 19

889:7x 127

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

2x 7x 13 = 182

Therefore, the value for common factors is 182.

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 = 65541133840/(1x182)

LCM = 65541133840/182

LCM = 360116120

Thus, we can understand that the LCM of 728,205,494,889 is 360116120.
