Given numbers are 407,170,545,71

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

The LCM of 407,170,545,71 is 535461410.

Find LCM of 407,170,545,71 with Prime Factorization

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

5 x 407 x 34 x 109 x 71 = 535461410

Therefore, the lowest common multiple of 407,170,545,71 is 535461410.

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.

407 x 170 x 545 x 71 = 2677307050

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.

407 : 1, 11, 37, 407

170 : 1, 2, 5, 10, 17, 34, 85, 170

545 : 1, 5, 109, 545

71 : 1, 71

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 407,170,545,71, is 1.

Now, the common factors can be found like this.

407:11x 37

170:2x 5x 17

545:5x 109

71:71

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

5 = 5

Therefore, the value for common factors is 5.

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 = 2677307050/(1x5)

LCM = 2677307050/5

LCM = 535461410

Thus, we can understand that the LCM of 407,170,545,71 is 535461410.
