Given numbers are 748,550,517,990

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

The LCM of 748,550,517,990 is 7910100.

Find LCM of 748,550,517,990 with Prime Factorization

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

2 x 5 x 11 x 34 x 5 x 47 x 9 = 7910100

Therefore, the lowest common multiple of 748,550,517,990 is 7910100.

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 550 x 517 x 990 = 210566862000

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

550 : 1, 2, 5, 10, 11, 22, 25, 50, 55, 110, 275, 550

517 : 1, 11, 47, 517

990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990

11 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 748,550,517,990, is 11.

Now, the common factors can be found like this.

748:2x 2x 11x 17

550:2x 5x 5x 11

517:11x 47

990:2x 3x 3x 5x 11

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 5x 11x 11 = 2420

Therefore, the value for common factors is 2420.

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 = 210566862000/(11x2420)

LCM = 210566862000/26620

LCM = 7910100

Thus, we can understand that the LCM of 748,550,517,990 is 7910100.
