Calculate the LCM of 401,878,532,146,128

Given numbers are 401,878,532,146,128

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

The LCM of 401,878,532,146,128 is 218772819328.

Find LCM of 401,878,532,146,128 with Prime Factorization


2 401, 878, 532, 146, 128
2 401, 439, 266, 73, 64
401, 439, 133, 73, 32

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

2 x 2 x 401 x 439 x 133 x 73 x 32 = 218772819328

Therefore, the lowest common multiple of 401,878,532,146,128 is 218772819328.

LCM Formula to Find Lowest Common Multiple of 401,878,532,146,128

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 878 x 532 x 146 x 128 = 3500365109248

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

878 : 1, 2, 439, 878

532 : 1, 2, 4, 7, 14, 19, 28, 38, 76, 133, 266, 532

146 : 1, 2, 73, 146

128 : 1, 2, 4, 8, 16, 32, 64, 128

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 401,878,532,146,128, is 1.

Now, the common factors can be found like this.

401:401

878:2x 439

532:2x 2x 7x 19

146:2x 73

128:2x 2x 2x 2x 2x 2x 2

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 2x 2 = 16

Therefore, the value for common factors is 16.

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 = 3500365109248/(1x16)

LCM = 3500365109248/16

LCM = 218772819328

Thus, we can understand that the LCM of 401,878,532,146,128 is 218772819328.
