Calculate the LCM of 307,634,410,921

Given numbers are 307,634,410,921

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

The LCM of 307,634,410,921 is 119702370.

Find LCM of 307,634,410,921 with Prime Factorization


2 307, 634, 410, 921
307 307, 317, 205, 921
1, 317, 205, 3

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

2 x 307 x 1 x 317 x 205 x 3 = 119702370

Therefore, the lowest common multiple of 307,634,410,921 is 119702370.

LCM Formula to Find Lowest Common Multiple of 307,634,410,921

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.

307 x 634 x 410 x 921 = 73497255180

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.

307 : 1, 307

634 : 1, 2, 317, 634

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

921 : 1, 3, 307, 921

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 307,634,410,921, is 1.

Now, the common factors can be found like this.

307:307

634:2x 317

410:2x 5x 41

921:3x 307

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

2x 307 = 614

Therefore, the value for common factors is 614.

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 = 73497255180/(1x614)

LCM = 73497255180/614

LCM = 119702370

Thus, we can understand that the LCM of 307,634,410,921 is 119702370.
