Calculate the LCM of 680,325,399,487

Given numbers are 680,325,399,487

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

The LCM of 680,325,399,487 is 8588634600.

Find LCM of 680,325,399,487 with Prime Factorization


5 680, 325, 399, 487
136, 65, 399, 487

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

5 x 136 x 65 x 399 x 487 = 8588634600

Therefore, the lowest common multiple of 680,325,399,487 is 8588634600.

LCM Formula to Find Lowest Common Multiple of 680,325,399,487

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 325 x 399 x 487 = 42943173000

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

325 : 1, 5, 13, 25, 65, 325

399 : 1, 3, 7, 19, 21, 57, 133, 399

487 : 1, 487

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 680,325,399,487, is 1.

Now, the common factors can be found like this.

680:2x 2x 2x 5x 17

325:5x 5x 13

399:3x 7x 19

487:487

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

5 = 5

Therefore, the value for common factors is 5.

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 = 42943173000/(1x5)

LCM = 42943173000/5

LCM = 8588634600

Thus, we can understand that the LCM of 680,325,399,487 is 8588634600.
