Calculate the LCM of 788,812,630,789

Given numbers are 788,812,630,789

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

The LCM of 788,812,630,789 is 1893173940.

Find LCM of 788,812,630,789 with Prime Factorization


2 788, 812, 630, 789
2 394, 406, 315, 789
3 197, 203, 315, 789
7 197, 203, 105, 263
197, 29, 15, 263

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

2 x 2 x 3 x 7 x 197 x 29 x 15 x 263 = 1893173940

Therefore, the lowest common multiple of 788,812,630,789 is 1893173940.

LCM Formula to Find Lowest Common Multiple of 788,812,630,789

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.

788 x 812 x 630 x 789 = 318053221920

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.

788 : 1, 2, 4, 197, 394, 788

812 : 1, 2, 4, 7, 14, 28, 29, 58, 116, 203, 406, 812

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

789 : 1, 3, 263, 789

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 788,812,630,789, is 1.

Now, the common factors can be found like this.

788:2x 2x 197

812:2x 2x 7x 29

630:2x 3x 3x 5x 7

789:3x 263

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 3x 7 = 168

Therefore, the value for common factors is 168.

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 = 318053221920/(1x168)

LCM = 318053221920/168

LCM = 1893173940

Thus, we can understand that the LCM of 788,812,630,789 is 1893173940.
