Given numbers are 781,341,407,786

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

The LCM of 781,341,407,786 is 704104302.

Find LCM of 781,341,407,786 with Prime Factorization

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

11 x 71 x 31 x 37 x 786 = 704104302

Therefore, the lowest common multiple of 781,341,407,786 is 704104302.

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 341 x 407 x 786 = 85196620542

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

341 : 1, 11, 31, 341

407 : 1, 11, 37, 407

786 : 1, 2, 3, 6, 131, 262, 393, 786

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 781,341,407,786, is 1.

Now, the common factors can be found like this.

781:11x 71

341:11x 31

407:11x 37

786:2x 3x 131

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

11x 11 = 121

Therefore, the value for common factors is 121.

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 = 85196620542/(1x121)

LCM = 85196620542/121

LCM = 704104302

Thus, we can understand that the LCM of 781,341,407,786 is 704104302.
