Calculate the LCM of 680,287,818,529

Given numbers are 680,287,818,529

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

The LCM of 680,287,818,529 is 42225012760.

Find LCM of 680,287,818,529 with Prime Factorization


2 680, 287, 818, 529
340, 287, 409, 529

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

2 x 340 x 287 x 409 x 529 = 42225012760

Therefore, the lowest common multiple of 680,287,818,529 is 42225012760.

LCM Formula to Find Lowest Common Multiple of 680,287,818,529

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 287 x 818 x 529 = 84450025520

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

287 : 1, 7, 41, 287

818 : 1, 2, 409, 818

529 : 1, 23, 529

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 680,287,818,529, is 1.

Now, the common factors can be found like this.

680:2x 2x 2x 5x 17

287:7x 41

818:2x 409

529:23x 23

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 = 84450025520/(1x2)

LCM = 84450025520/2

LCM = 42225012760

Thus, we can understand that the LCM of 680,287,818,529 is 42225012760.
