Given numbers are 786,396,402,857

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

The LCM of 786,396,402,857 is 2978668044.

Find LCM of 786,396,402,857 with Prime Factorization

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

2 x 3 x 131 x 66 x 67 x 857 = 2978668044

Therefore, the lowest common multiple of 786,396,402,857 is 2978668044.

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.

786 x 396 x 402 x 857 = 107232049584

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.

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

396 : 1, 2, 3, 4, 6, 9, 11, 12, 18, 22, 33, 36, 44, 66, 99, 132, 198, 396

402 : 1, 2, 3, 6, 67, 134, 201, 402

857 : 1, 857

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 786,396,402,857, is 1.

Now, the common factors can be found like this.

786:2x 3x 131

396:2x 2x 3x 3x 11

402:2x 3x 67

857:857

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

2x 2x 3x 3 = 36

Therefore, the value for common factors is 36.

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 = 107232049584/(1x36)

LCM = 107232049584/36

LCM = 2978668044

Thus, we can understand that the LCM of 786,396,402,857 is 2978668044.
