Calculate the LCM of 638,452,410,903

Given numbers are 638,452,410,903

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

The LCM of 638,452,410,903 is 26691361620.

Find LCM of 638,452,410,903 with Prime Factorization


2 638, 452, 410, 903
319, 226, 205, 903

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

2 x 319 x 226 x 205 x 903 = 26691361620

Therefore, the lowest common multiple of 638,452,410,903 is 26691361620.

LCM Formula to Find Lowest Common Multiple of 638,452,410,903

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.

638 x 452 x 410 x 903 = 106765446480

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.

638 : 1, 2, 11, 22, 29, 58, 319, 638

452 : 1, 2, 4, 113, 226, 452

410 : 1, 2, 5, 10, 41, 82, 205, 410

903 : 1, 3, 7, 21, 43, 129, 301, 903

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 638,452,410,903, is 1.

Now, the common factors can be found like this.

638:2x 11x 29

452:2x 2x 113

410:2x 5x 41

903:3x 7x 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 2 = 4

Therefore, the value for common factors is 4.

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 = 106765446480/(1x4)

LCM = 106765446480/4

LCM = 26691361620

Thus, we can understand that the LCM of 638,452,410,903 is 26691361620.
