Calculate the LCM of 756,678,556,452

Given numbers are 756,678,556,452

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

The LCM of 756,678,556,452 is 11874492.

Find LCM of 756,678,556,452 with Prime Factorization


2 756, 678, 556, 452
2 378, 339, 278, 226
3 189, 339, 139, 113
113 63, 113, 139, 113
63, 1, 139, 1

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

2 x 2 x 3 x 113 x 63 x 1 x 139 x 1 = 11874492

Therefore, the lowest common multiple of 756,678,556,452 is 11874492.

LCM Formula to Find Lowest Common Multiple of 756,678,556,452

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.

756 x 678 x 556 x 452 = 128814489216

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.

756 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 27, 28, 36, 42, 54, 63, 84, 108, 126, 189, 252, 378, 756

678 : 1, 2, 3, 6, 113, 226, 339, 678

556 : 1, 2, 4, 139, 278, 556

452 : 1, 2, 4, 113, 226, 452

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 756,678,556,452, is 2.

Now, the common factors can be found like this.

756:2x 2x 3x 3x 3x 7

678:2x 3x 113

556:2x 2x 139

452:2x 2x 113

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 2x 2x 3x 113 = 5424

Therefore, the value for common factors is 5424.

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 = 128814489216/(2x5424)

LCM = 128814489216/10848

LCM = 11874492

Thus, we can understand that the LCM of 756,678,556,452 is 11874492.
