Given numbers are 170,138,364,853

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

The LCM of 170,138,364,853 is 1821035580.

Find LCM of 170,138,364,853 with Prime Factorization

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

2 x 85 x 69 x 182 x 853 = 1821035580

Therefore, the lowest common multiple of 170,138,364,853 is 1821035580.

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.

170 x 138 x 364 x 853 = 7284142320

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.

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

138 : 1, 2, 3, 6, 23, 46, 69, 138

364 : 1, 2, 4, 7, 13, 14, 26, 28, 52, 91, 182, 364

853 : 1, 853

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 170,138,364,853, is 1.

Now, the common factors can be found like this.

170:2x 5x 17

138:2x 3x 23

364:2x 2x 7x 13

853:853

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 = 7284142320/(1x4)

LCM = 7284142320/4

LCM = 1821035580

Thus, we can understand that the LCM of 170,138,364,853 is 1821035580.
