Given numbers are 781,122,473,411

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

The LCM of 781,122,473,411 is 1683918786.

Find LCM of 781,122,473,411 with Prime Factorization

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

11 x 71 x 122 x 43 x 411 = 1683918786

Therefore, the lowest common multiple of 781,122,473,411 is 1683918786.

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 122 x 473 x 411 = 18523106646

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

122 : 1, 2, 61, 122

473 : 1, 11, 43, 473

411 : 1, 3, 137, 411

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 781,122,473,411, is 1.

Now, the common factors can be found like this.

781:11x 71

122:2x 61

473:11x 43

411:3x 137

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

11 = 11

Therefore, the value for common factors is 11.

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 = 18523106646/(1x11)

LCM = 18523106646/11

LCM = 1683918786

Thus, we can understand that the LCM of 781,122,473,411 is 1683918786.
