Given numbers are 391,436,497,697

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

The LCM of 391,436,497,697 is 3473789452.

Find LCM of 391,436,497,697 with Prime Factorization

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

17 x 23 x 436 x 497 x 41 = 3473789452

Therefore, the lowest common multiple of 391,436,497,697 is 3473789452.

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.

391 x 436 x 497 x 697 = 59054420684

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.

391 : 1, 17, 23, 391

436 : 1, 2, 4, 109, 218, 436

497 : 1, 7, 71, 497

697 : 1, 17, 41, 697

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 391,436,497,697, is 1.

Now, the common factors can be found like this.

391:17x 23

436:2x 2x 109

497:7x 71

697:17x 41

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

17 = 17

Therefore, the value for common factors is 17.

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 = 59054420684/(1x17)

LCM = 59054420684/17

LCM = 3473789452

Thus, we can understand that the LCM of 391,436,497,697 is 3473789452.
