LCM of:

Calculate the LCM of 423,978,505

Given numbers are 423,978,505

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

The LCM of 423,978,505 is 69638490.

Find LCM of 423,978,505 with Prime Factorization


3 423, 978, 505
141, 326, 505

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

3 x 141 x 326 x 505 = 69638490

Therefore, the lowest common multiple of 423,978,505 is 69638490.

LCM Formula to Find Lowest Common Multiple of 423,978,505

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.

423 x 978 x 505 = 208915470

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.

423 : 1, 3, 9, 47, 141, 423

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

505 : 1, 5, 101, 505

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 423,978,505, is 1.

Now, the common factors can be found like this.

423:3x 3x 47

978:2x 3x 163

505:5x 101

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 = 208915470/(1x3)

LCM = 208915470/3

LCM = 69638490

Thus, we can understand that the LCM of 423,978,505 is 69638490.
