Given numbers are 781,497,351,528

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

The LCM of 781,497,351,528 is 30702672.

Find LCM of 781,497,351,528 with Prime Factorization

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

3 x 11 x 71 x 1 x 7 x 117 x 16 = 30702672

Therefore, the lowest common multiple of 781,497,351,528 is 30702672.

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.

781 x 497 x 351 x 528 = 71936360496

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.

781 : 1, 11, 71, 781

497 : 1, 7, 71, 497

351 : 1, 3, 9, 13, 27, 39, 117, 351

528 : 1, 2, 3, 4, 6, 8, 11, 12, 16, 22, 24, 33, 44, 48, 66, 88, 132, 176, 264, 528

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 781,497,351,528, is 1.

Now, the common factors can be found like this.

781:11x 71

497:7x 71

351:3x 3x 3x 13

528:2x 2x 2x 2x 3x 11

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

3x 11x 71 = 2343

Therefore, the value for common factors is 2343.

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 = 71936360496/(1x2343)

LCM = 71936360496/2343

LCM = 30702672

Thus, we can understand that the LCM of 781,497,351,528 is 30702672.
