Calculate the LCM of 678,630,514,665

Given numbers are 678,630,514,665

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

The LCM of 678,630,514,665 is 347620770.

Find LCM of 678,630,514,665 with Prime Factorization


2 678, 630, 514, 665
3 339, 315, 257, 665
5 113, 105, 257, 665
7 113, 21, 257, 133
113, 3, 257, 19

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

2 x 3 x 5 x 7 x 113 x 3 x 257 x 19 = 347620770

Therefore, the lowest common multiple of 678,630,514,665 is 347620770.

LCM Formula to Find Lowest Common Multiple of 678,630,514,665

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.

678 x 630 x 514 x 665 = 146000723400

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.

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

630 : 1, 2, 3, 5, 6, 7, 9, 10, 14, 15, 18, 21, 30, 35, 42, 45, 63, 70, 90, 105, 126, 210, 315, 630

514 : 1, 2, 257, 514

665 : 1, 5, 7, 19, 35, 95, 133, 665

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 678,630,514,665, is 1.

Now, the common factors can be found like this.

678:2x 3x 113

630:2x 3x 3x 5x 7

514:2x 257

665:5x 7x 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 2x 3x 5x 7 = 420

Therefore, the value for common factors is 420.

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 = 146000723400/(1x420)

LCM = 146000723400/420

LCM = 347620770

Thus, we can understand that the LCM of 678,630,514,665 is 347620770.
