Given numbers are 688,165,511,279,473

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

The LCM of 688,165,511,279,473 is 5394810960.

Find LCM of 688,165,511,279,473 with Prime Factorization

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

3 x 11 x 43 x 16 x 5 x 511 x 93 x 1 = 5394810960

Therefore, the lowest common multiple of 688,165,511,279,473 is 5394810960.

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.

688 x 165 x 511 x 279 x 473 = 7655236752240

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.

688 : 1, 2, 4, 8, 16, 43, 86, 172, 344, 688

165 : 1, 3, 5, 11, 15, 33, 55, 165

511 : 1, 7, 73, 511

279 : 1, 3, 9, 31, 93, 279

473 : 1, 11, 43, 473

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 688,165,511,279,473, is 1.

Now, the common factors can be found like this.

688:2x 2x 2x 2x 43

165:3x 5x 11

511:7x 73

279:3x 3x 31

473:11x 43

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

3x 11x 43 = 1419

Therefore, the value for common factors is 1419.

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 = 7655236752240/(1x1419)

LCM = 7655236752240/1419

LCM = 5394810960

Thus, we can understand that the LCM of 688,165,511,279,473 is 5394810960.
