Given numbers are 781,654,280

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

The LCM of 781,654,280 is 71508360.

Find LCM of 781,654,280 with Prime Factorization

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

2 x 781 x 327 x 140 = 71508360

Therefore, the lowest common multiple of 781,654,280 is 71508360.

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 654 x 280 = 143016720

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

654 : 1, 2, 3, 6, 109, 218, 327, 654

280 : 1, 2, 4, 5, 7, 8, 10, 14, 20, 28, 35, 40, 56, 70, 140, 280

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 781,654,280, is 1.

Now, the common factors can be found like this.

781:11x 71

654:2x 3x 109

280:2x 2x 2x 5x 7

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

2 = 2

Therefore, the value for common factors is 2.

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 = 143016720/(1x2)

LCM = 143016720/2

LCM = 71508360

Thus, we can understand that the LCM of 781,654,280 is 71508360.
