Calculate the LCM of 642,788,230,847

Given numbers are 642,788,230,847

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

The LCM of 642,788,230,847 is 24638399940.

Find LCM of 642,788,230,847 with Prime Factorization


2 642, 788, 230, 847
321, 394, 115, 847

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

2 x 321 x 394 x 115 x 847 = 24638399940

Therefore, the lowest common multiple of 642,788,230,847 is 24638399940.

LCM Formula to Find Lowest Common Multiple of 642,788,230,847

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.

642 x 788 x 230 x 847 = 98553599760

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.

642 : 1, 2, 3, 6, 107, 214, 321, 642

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

230 : 1, 2, 5, 10, 23, 46, 115, 230

847 : 1, 7, 11, 77, 121, 847

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 642,788,230,847, is 1.

Now, the common factors can be found like this.

642:2x 3x 107

788:2x 2x 197

230:2x 5x 23

847:7x 11x 11

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 98553599760/(1x4)

LCM = 98553599760/4

LCM = 24638399940

Thus, we can understand that the LCM of 642,788,230,847 is 24638399940.
