Given numbers are 257,771,689,649

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

The LCM of 257,771,689,649 is 344761131.

Find LCM of 257,771,689,649 with Prime Factorization

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

257 x 1 x 3 x 689 x 649 = 344761131

Therefore, the lowest common multiple of 257,771,689,649 is 344761131.

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.

257 x 771 x 689 x 649 = 88603610667

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.

257 : 1, 257

771 : 1, 3, 257, 771

689 : 1, 13, 53, 689

649 : 1, 11, 59, 649

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 257,771,689,649, is 1.

Now, the common factors can be found like this.

257:257

771:3x 257

689:13x 53

649:11x 59

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

257 = 257

Therefore, the value for common factors is 257.

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 = 88603610667/(1x257)

LCM = 88603610667/257

LCM = 344761131

Thus, we can understand that the LCM of 257,771,689,649 is 344761131.
