Given numbers are 644,695,479,246,257

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

The LCM of 644,695,479,246,257 is 6777108211020.

Find LCM of 644,695,479,246,257 with Prime Factorization

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

2 x 322 x 695 x 479 x 123 x 257 = 6777108211020

Therefore, the lowest common multiple of 644,695,479,246,257 is 6777108211020.

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.

644 x 695 x 479 x 246 x 257 = 13554216422040

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.

644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644

695 : 1, 5, 139, 695

479 : 1, 479

246 : 1, 2, 3, 6, 41, 82, 123, 246

257 : 1, 257

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 644,695,479,246,257, is 1.

Now, the common factors can be found like this.

644:2x 2x 7x 23

695:5x 139

479:479

246:2x 3x 41

257:257

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

2 = 2

Therefore, the value for common factors is 2.

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 = 13554216422040/(1x2)

LCM = 13554216422040/2

LCM = 6777108211020

Thus, we can understand that the LCM of 644,695,479,246,257 is 6777108211020.
