Given numbers are 748,638,424,306

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

The LCM of 748,638,424,306 is 20694168.

Find LCM of 748,638,424,306 with Prime Factorization

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

2 x 2 x 11 x 17 x 1 x 29 x 106 x 9 = 20694168

Therefore, the lowest common multiple of 748,638,424,306 is 20694168.

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.

748 x 638 x 424 x 306 = 61916950656

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.

748 : 1, 2, 4, 11, 17, 22, 34, 44, 68, 187, 374, 748

638 : 1, 2, 11, 22, 29, 58, 319, 638

424 : 1, 2, 4, 8, 53, 106, 212, 424

306 : 1, 2, 3, 6, 9, 17, 18, 34, 51, 102, 153, 306

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 748,638,424,306, is 2.

Now, the common factors can be found like this.

748:2x 2x 11x 17

638:2x 11x 29

424:2x 2x 2x 53

306:2x 3x 3x 17

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 2x 11x 17 = 1496

Therefore, the value for common factors is 1496.

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 = 61916950656/(2x1496)

LCM = 61916950656/2992

LCM = 20694168

Thus, we can understand that the LCM of 748,638,424,306 is 20694168.
