Given numbers are 417,434,865,865

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

The LCM of 417,434,865,865 is 156545970.

Find LCM of 417,434,865,865 with Prime Factorization

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

5 x 173 x 417 x 434 x 1 x 1 = 156545970

Therefore, the lowest common multiple of 417,434,865,865 is 156545970.

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.

417 x 434 x 865 x 865 = 135412264050

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.

417 : 1, 3, 139, 417

434 : 1, 2, 7, 14, 31, 62, 217, 434

865 : 1, 5, 173, 865

865 : 1, 5, 173, 865

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 417,434,865,865, is 1.

Now, the common factors can be found like this.

417:3x 139

434:2x 7x 31

865:5x 173

865:5x 173

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

5x 173 = 865

Therefore, the value for common factors is 865.

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 = 135412264050/(1x865)

LCM = 135412264050/865

LCM = 156545970

Thus, we can understand that the LCM of 417,434,865,865 is 156545970.
