Given numbers are 626,630,268,658

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

The LCM of 626,630,268,658 is 1241902620.

Find LCM of 626,630,268,658 with Prime Factorization

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

2 x 7 x 313 x 45 x 134 x 47 = 1241902620

Therefore, the lowest common multiple of 626,630,268,658 is 1241902620.

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.

626 x 630 x 268 x 658 = 69546546720

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.

626 : 1, 2, 313, 626

630 : 1, 2, 3, 5, 6, 7, 9, 10, 14, 15, 18, 21, 30, 35, 42, 45, 63, 70, 90, 105, 126, 210, 315, 630

268 : 1, 2, 4, 67, 134, 268

658 : 1, 2, 7, 14, 47, 94, 329, 658

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 626,630,268,658, is 2.

Now, the common factors can be found like this.

626:2x 313

630:2x 3x 3x 5x 7

268:2x 2x 67

658:2x 7x 47

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 7 = 28

Therefore, the value for common factors is 28.

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 = 69546546720/(2x28)

LCM = 69546546720/56

LCM = 1241902620

Thus, we can understand that the LCM of 626,630,268,658 is 1241902620.
