Given numbers are 433,990,434,781

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

The LCM of 433,990,434,781 is 6604518690.

Find LCM of 433,990,434,781 with Prime Factorization

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

2 x 11 x 433 x 45 x 217 x 71 = 6604518690

Therefore, the lowest common multiple of 433,990,434,781 is 6604518690.

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.

433 x 990 x 434 x 781 = 145299411180

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.

433 : 1, 433

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

434 : 1, 2, 7, 14, 31, 62, 217, 434

781 : 1, 11, 71, 781

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 433,990,434,781, is 1.

Now, the common factors can be found like this.

433:433

990:2x 3x 3x 5x 11

434:2x 7x 31

781:11x 71

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

2x 11 = 22

Therefore, the value for common factors is 22.

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 = 145299411180/(1x22)

LCM = 145299411180/22

LCM = 6604518690

Thus, we can understand that the LCM of 433,990,434,781 is 6604518690.
