Given numbers are 317,116,157,686

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

The LCM of 317,116,157,686 is 1980208972.

Find LCM of 317,116,157,686 with Prime Factorization

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

2 x 317 x 58 x 157 x 343 = 1980208972

Therefore, the lowest common multiple of 317,116,157,686 is 1980208972.

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.

317 x 116 x 157 x 686 = 3960417944

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.

317 : 1, 317

116 : 1, 2, 4, 29, 58, 116

157 : 1, 157

686 : 1, 2, 7, 14, 49, 98, 343, 686

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 317,116,157,686, is 1.

Now, the common factors can be found like this.

317:317

116:2x 2x 29

157:157

686:2x 7x 7x 7

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

2 = 2

Therefore, the value for common factors is 2.

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 = 3960417944/(1x2)

LCM = 3960417944/2

LCM = 1980208972

Thus, we can understand that the LCM of 317,116,157,686 is 1980208972.
