Calculate the LCM of 728,151,338,145

Given numbers are 728,151,338,145

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

The LCM of 728,151,338,145 is 207214280.

Find LCM of 728,151,338,145 with Prime Factorization


2 728, 151, 338, 145
13 364, 151, 169, 145
28, 151, 13, 145

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

2 x 13 x 28 x 151 x 13 x 145 = 207214280

Therefore, the lowest common multiple of 728,151,338,145 is 207214280.

LCM Formula to Find Lowest Common Multiple of 728,151,338,145

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 151 x 338 x 145 = 5387571280

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

151 : 1, 151

338 : 1, 2, 13, 26, 169, 338

145 : 1, 5, 29, 145

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 728,151,338,145, is 1.

Now, the common factors can be found like this.

728:2x 2x 2x 7x 13

151:151

338:2x 13x 13

145:5x 29

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

2x 13 = 26

Therefore, the value for common factors is 26.

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 = 5387571280/(1x26)

LCM = 5387571280/26

LCM = 207214280

Thus, we can understand that the LCM of 728,151,338,145 is 207214280.
