Calculate the LCM of 381,489,978,829

Given numbers are 381,489,978,829

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

The LCM of 381,489,978,829 is 102966774.

Find LCM of 381,489,978,829 with Prime Factorization


3 381, 489, 978, 829
163 127, 163, 326, 829
127, 1, 2, 829

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

3 x 163 x 127 x 1 x 2 x 829 = 102966774

Therefore, the lowest common multiple of 381,489,978,829 is 102966774.

LCM Formula to Find Lowest Common Multiple of 381,489,978,829

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.

381 x 489 x 978 x 829 = 151052257458

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.

381 : 1, 3, 127, 381

489 : 1, 3, 163, 489

978 : 1, 2, 3, 6, 163, 326, 489, 978

829 : 1, 829

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 381,489,978,829, is 1.

Now, the common factors can be found like this.

381:3x 127

489:3x 163

978:2x 3x 163

829:829

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

3x 3x 163 = 1467

Therefore, the value for common factors is 1467.

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 = 151052257458/(1x1467)

LCM = 151052257458/1467

LCM = 102966774

Thus, we can understand that the LCM of 381,489,978,829 is 102966774.
