Calculate the LCM of 664,804,782,989

Given numbers are 664,804,782,989

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

The LCM of 664,804,782,989 is 2243930232.

Find LCM of 664,804,782,989 with Prime Factorization


2 664, 804, 782, 989
2 332, 402, 391, 989
23 166, 201, 391, 989
166, 201, 17, 43

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

2 x 2 x 23 x 166 x 201 x 17 x 43 = 2243930232

Therefore, the lowest common multiple of 664,804,782,989 is 2243930232.

LCM Formula to Find Lowest Common Multiple of 664,804,782,989

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.

664 x 804 x 782 x 989 = 412883162688

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.

664 : 1, 2, 4, 8, 83, 166, 332, 664

804 : 1, 2, 3, 4, 6, 12, 67, 134, 201, 268, 402, 804

782 : 1, 2, 17, 23, 34, 46, 391, 782

989 : 1, 23, 43, 989

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 664,804,782,989, is 1.

Now, the common factors can be found like this.

664:2x 2x 2x 83

804:2x 2x 3x 67

782:2x 17x 23

989:23x 43

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 23 = 184

Therefore, the value for common factors is 184.

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 = 412883162688/(1x184)

LCM = 412883162688/184

LCM = 2243930232

Thus, we can understand that the LCM of 664,804,782,989 is 2243930232.
