Calculate the LCM of 697,391,887,289,432

Given numbers are 697,391,887,289,432

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

The LCM of 697,391,887,289,432 is 104427985968.

Find LCM of 697,391,887,289,432 with Prime Factorization


17 697, 391, 887, 289, 432
41, 23, 887, 17, 432

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

17 x 41 x 23 x 887 x 17 x 432 = 104427985968

Therefore, the lowest common multiple of 697,391,887,289,432 is 104427985968.

LCM Formula to Find Lowest Common Multiple of 697,391,887,289,432

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.

697 x 391 x 887 x 289 x 432 = 30179687944752

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.

697 : 1, 17, 41, 697

391 : 1, 17, 23, 391

887 : 1, 887

289 : 1, 17, 289

432 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 27, 36, 48, 54, 72, 108, 144, 216, 432

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 697,391,887,289,432, is 1.

Now, the common factors can be found like this.

697:17x 41

391:17x 23

887:887

289:17x 17

432:2x 2x 2x 2x 3x 3x 3

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

17x 17 = 289

Therefore, the value for common factors is 289.

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 = 30179687944752/(1x289)

LCM = 30179687944752/289

LCM = 104427985968

Thus, we can understand that the LCM of 697,391,887,289,432 is 104427985968.
