Calculate the LCM of 287,514,443,434,280

Given numbers are 287,514,443,434,280

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

The LCM of 287,514,443,434,280 is 40517293880.

Find LCM of 287,514,443,434,280 with Prime Factorization


2 287, 514, 443, 434, 280
7 287, 257, 443, 217, 140
41, 257, 443, 31, 20

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

2 x 7 x 41 x 257 x 443 x 31 x 20 = 40517293880

Therefore, the lowest common multiple of 287,514,443,434,280 is 40517293880.

LCM Formula to Find Lowest Common Multiple of 287,514,443,434,280

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.

287 x 514 x 443 x 434 x 280 = 7941389600480

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.

287 : 1, 7, 41, 287

514 : 1, 2, 257, 514

443 : 1, 443

434 : 1, 2, 7, 14, 31, 62, 217, 434

280 : 1, 2, 4, 5, 7, 8, 10, 14, 20, 28, 35, 40, 56, 70, 140, 280

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 287,514,443,434,280, is 1.

Now, the common factors can be found like this.

287:7x 41

514:2x 257

443:443

434:2x 7x 31

280:2x 2x 2x 5x 7

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 7x 7 = 196

Therefore, the value for common factors is 196.

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 = 7941389600480/(1x196)

LCM = 7941389600480/196

LCM = 40517293880

Thus, we can understand that the LCM of 287,514,443,434,280 is 40517293880.
