Calculate the LCM of 401,865,370,634

Given numbers are 401,865,370,634

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

The LCM of 401,865,370,634 is 8136759170.

Find LCM of 401,865,370,634 with Prime Factorization


2 401, 865, 370, 634
5 401, 865, 185, 317
401, 173, 37, 317

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

2 x 5 x 401 x 173 x 37 x 317 = 8136759170

Therefore, the lowest common multiple of 401,865,370,634 is 8136759170.

LCM Formula to Find Lowest Common Multiple of 401,865,370,634

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.

401 x 865 x 370 x 634 = 81367591700

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.

401 : 1, 401

865 : 1, 5, 173, 865

370 : 1, 2, 5, 10, 37, 74, 185, 370

634 : 1, 2, 317, 634

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 401,865,370,634, is 1.

Now, the common factors can be found like this.

401:401

865:5x 173

370:2x 5x 37

634:2x 317

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

2x 5 = 10

Therefore, the value for common factors is 10.

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 = 81367591700/(1x10)

LCM = 81367591700/10

LCM = 8136759170

Thus, we can understand that the LCM of 401,865,370,634 is 8136759170.
