Calculate the LCM of 646,889,809,889

Given numbers are 646,889,809,889

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

The LCM of 646,889,809,889 is 464603846.

Find LCM of 646,889,809,889 with Prime Factorization


7 646, 889, 809, 889
127 646, 127, 809, 127
646, 1, 809, 1

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

7 x 127 x 646 x 1 x 809 x 1 = 464603846

Therefore, the lowest common multiple of 646,889,809,889 is 464603846.

LCM Formula to Find Lowest Common Multiple of 646,889,809,889

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.

646 x 889 x 809 x 889 = 413032819094

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.

646 : 1, 2, 17, 19, 34, 38, 323, 646

889 : 1, 7, 127, 889

809 : 1, 809

889 : 1, 7, 127, 889

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 646,889,809,889, is 1.

Now, the common factors can be found like this.

646:2x 17x 19

889:7x 127

809:809

889:7x 127

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

7x 127 = 889

Therefore, the value for common factors is 889.

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 = 413032819094/(1x889)

LCM = 413032819094/889

LCM = 464603846

Thus, we can understand that the LCM of 646,889,809,889 is 464603846.
