Given numbers are 680,271,276,121

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

The LCM of 680,271,276,121 is 1538553720.

Find LCM of 680,271,276,121 with Prime Factorization

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

2 x 2 x 170 x 271 x 69 x 121 = 1538553720

Therefore, the lowest common multiple of 680,271,276,121 is 1538553720.

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.

680 x 271 x 276 x 121 = 6154214880

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.

680 : 1, 2, 4, 5, 8, 10, 17, 20, 34, 40, 68, 85, 136, 170, 340, 680

271 : 1, 271

276 : 1, 2, 3, 4, 6, 12, 23, 46, 69, 92, 138, 276

121 : 1, 11, 121

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 680,271,276,121, is 1.

Now, the common factors can be found like this.

680:2x 2x 2x 5x 17

271:271

276:2x 2x 3x 23

121:11x 11

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 6154214880/(1x4)

LCM = 6154214880/4

LCM = 1538553720

Thus, we can understand that the LCM of 680,271,276,121 is 1538553720.

Here are some samples of LCM of two or more Numbers calculations.

• LCM of 205, 174, 968, 595
