Given numbers are 785,346,628,161

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

The LCM of 785,346,628,161 is 87458420.

Find LCM of 785,346,628,161 with Prime Factorization

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

2 x 157 x 5 x 173 x 2 x 161 = 87458420

Therefore, the lowest common multiple of 785,346,628,161 is 87458420.

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.

785 x 346 x 628 x 161 = 27461943880

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.

785 : 1, 5, 157, 785

346 : 1, 2, 173, 346

628 : 1, 2, 4, 157, 314, 628

161 : 1, 7, 23, 161

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 785,346,628,161, is 1.

Now, the common factors can be found like this.

785:5x 157

346:2x 173

628:2x 2x 157

161:7x 23

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

2x 157 = 314

Therefore, the value for common factors is 314.

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 = 27461943880/(1x314)

LCM = 27461943880/314

LCM = 87458420

Thus, we can understand that the LCM of 785,346,628,161 is 87458420.
