Given numbers are 717,781,149,142

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

The LCM of 717,781,149,142 is 166873146.

Find LCM of 717,781,149,142 with Prime Factorization

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

71 x 717 x 11 x 149 x 2 = 166873146

Therefore, the lowest common multiple of 717,781,149,142 is 166873146.

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.

717 x 781 x 149 x 142 = 11847993366

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.

717 : 1, 3, 239, 717

781 : 1, 11, 71, 781

149 : 1, 149

142 : 1, 2, 71, 142

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 717,781,149,142, is 1.

Now, the common factors can be found like this.

717:3x 239

781:11x 71

149:149

142:2x 71

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

71 = 71

Therefore, the value for common factors is 71.

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 = 11847993366/(1x71)

LCM = 11847993366/71

LCM = 166873146

Thus, we can understand that the LCM of 717,781,149,142 is 166873146.
