Calculate the LCM of 678,488,400,328,254

Given numbers are 678,488,400,328,254

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

The LCM of 678,488,400,328,254 is 43070221200.

Find LCM of 678,488,400,328,254 with Prime Factorization


2 678, 488, 400, 328, 254
2 339, 244, 200, 164, 127
2 339, 122, 100, 82, 127
339, 61, 50, 41, 127

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

2 x 2 x 2 x 339 x 61 x 50 x 41 x 127 = 43070221200

Therefore, the lowest common multiple of 678,488,400,328,254 is 43070221200.

LCM Formula to Find Lowest Common Multiple of 678,488,400,328,254

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.

678 x 488 x 400 x 328 x 254 = 11025976627200

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.

678 : 1, 2, 3, 6, 113, 226, 339, 678

488 : 1, 2, 4, 8, 61, 122, 244, 488

400 : 1, 2, 4, 5, 8, 10, 16, 20, 25, 40, 50, 80, 100, 200, 400

328 : 1, 2, 4, 8, 41, 82, 164, 328

254 : 1, 2, 127, 254

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 678,488,400,328,254, is 2.

Now, the common factors can be found like this.

678:2x 3x 113

488:2x 2x 2x 61

400:2x 2x 2x 2x 5x 5

328:2x 2x 2x 41

254:2x 127

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 2x 2x 2x 2 = 128

Therefore, the value for common factors is 128.

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 = 11025976627200/(2x128)

LCM = 11025976627200/256

LCM = 43070221200

Thus, we can understand that the LCM of 678,488,400,328,254 is 43070221200.
