Calculate the LCM of 401,904,203,912

Given numbers are 401,904,203,912

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

The LCM of 401,904,203,912 is 8389067568.

Find LCM of 401,904,203,912 with Prime Factorization


2 401, 904, 203, 912
2 401, 452, 203, 456
2 401, 226, 203, 228
401, 113, 203, 114

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

2 x 2 x 2 x 401 x 113 x 203 x 114 = 8389067568

Therefore, the lowest common multiple of 401,904,203,912 is 8389067568.

LCM Formula to Find Lowest Common Multiple of 401,904,203,912

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 904 x 203 x 912 = 67112540544

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

904 : 1, 2, 4, 8, 113, 226, 452, 904

203 : 1, 7, 29, 203

912 : 1, 2, 3, 4, 6, 8, 12, 16, 19, 24, 38, 48, 57, 76, 114, 152, 228, 304, 456, 912

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 401,904,203,912, is 1.

Now, the common factors can be found like this.

401:401

904:2x 2x 2x 113

203:7x 29

912:2x 2x 2x 2x 3x 19

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

2x 2x 2 = 8

Therefore, the value for common factors is 8.

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 = 67112540544/(1x8)

LCM = 67112540544/8

LCM = 8389067568

Thus, we can understand that the LCM of 401,904,203,912 is 8389067568.
