Calculate the LCM of 680,367,170,858

Given numbers are 680,367,170,858

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

The LCM of 680,367,170,858 is 107061240.

Find LCM of 680,367,170,858 with Prime Factorization


2 680, 367, 170, 858
5 340, 367, 85, 429
17 68, 367, 17, 429
4, 367, 1, 429

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

2 x 5 x 17 x 4 x 367 x 1 x 429 = 107061240

Therefore, the lowest common multiple of 680,367,170,858 is 107061240.

LCM Formula to Find Lowest Common Multiple of 680,367,170,858

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 367 x 170 x 858 = 36400821600

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

367 : 1, 367

170 : 1, 2, 5, 10, 17, 34, 85, 170

858 : 1, 2, 3, 6, 11, 13, 22, 26, 33, 39, 66, 78, 143, 286, 429, 858

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 680,367,170,858, is 1.

Now, the common factors can be found like this.

680:2x 2x 2x 5x 17

367:367

170:2x 5x 17

858:2x 3x 11x 13

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

2x 2x 5x 17 = 340

Therefore, the value for common factors is 340.

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 = 36400821600/(1x340)

LCM = 36400821600/340

LCM = 107061240

Thus, we can understand that the LCM of 680,367,170,858 is 107061240.
