Given numbers are 781,686,762,579

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

The LCM of 781,686,762,579 is 39396481278.

Find LCM of 781,686,762,579 with Prime Factorization

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

2 x 3 x 781 x 343 x 127 x 193 = 39396481278

Therefore, the lowest common multiple of 781,686,762,579 is 39396481278.

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 686 x 762 x 579 = 236378887668

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

686 : 1, 2, 7, 14, 49, 98, 343, 686

762 : 1, 2, 3, 6, 127, 254, 381, 762

579 : 1, 3, 193, 579

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 781,686,762,579, is 1.

Now, the common factors can be found like this.

781:11x 71

686:2x 7x 7x 7

762:2x 3x 127

579:3x 193

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

2x 3 = 6

Therefore, the value for common factors is 6.

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 = 236378887668/(1x6)

LCM = 236378887668/6

LCM = 39396481278

Thus, we can understand that the LCM of 781,686,762,579 is 39396481278.
