Calculate the LCM of 398,789,641,807

Given numbers are 398,789,641,807

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

The LCM of 398,789,641,807 is 54146499438.

Find LCM of 398,789,641,807 with Prime Factorization


3 398, 789, 641, 807
398, 263, 641, 269

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

3 x 398 x 263 x 641 x 269 = 54146499438

Therefore, the lowest common multiple of 398,789,641,807 is 54146499438.

LCM Formula to Find Lowest Common Multiple of 398,789,641,807

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.

398 x 789 x 641 x 807 = 162439498314

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.

398 : 1, 2, 199, 398

789 : 1, 3, 263, 789

641 : 1, 641

807 : 1, 3, 269, 807

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 398,789,641,807, is 1.

Now, the common factors can be found like this.

398:2x 199

789:3x 263

641:641

807:3x 269

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

3 = 3

Therefore, the value for common factors is 3.

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 = 162439498314/(1x3)

LCM = 162439498314/3

LCM = 54146499438

Thus, we can understand that the LCM of 398,789,641,807 is 54146499438.
