Given numbers are 434,561,403,697,391

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

The LCM of 434,561,403,697,391 is 2984747766.

Find LCM of 434,561,403,697,391 with Prime Factorization

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

17 x 31 x 14 x 33 x 13 x 41 x 23 = 2984747766

Therefore, the lowest common multiple of 434,561,403,697,391 is 2984747766.

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.

434 x 561 x 403 x 697 x 391 = 26740355235594

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.

434 : 1, 2, 7, 14, 31, 62, 217, 434

561 : 1, 3, 11, 17, 33, 51, 187, 561

403 : 1, 13, 31, 403

697 : 1, 17, 41, 697

391 : 1, 17, 23, 391

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 434,561,403,697,391, is 1.

Now, the common factors can be found like this.

434:2x 7x 31

561:3x 11x 17

403:13x 31

697:17x 41

391:17x 23

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

17x 17x 31 = 8959

Therefore, the value for common factors is 8959.

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 = 26740355235594/(1x8959)

LCM = 26740355235594/8959

LCM = 2984747766

Thus, we can understand that the LCM of 434,561,403,697,391 is 2984747766.
