Given numbers are 697,391,391,458

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

The LCM of 697,391,391,458 is 7342198.

Find LCM of 697,391,391,458 with Prime Factorization

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

17 x 23 x 41 x 1 x 1 x 458 = 7342198

Therefore, the lowest common multiple of 697,391,391,458 is 7342198.

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 391 x 458 = 48803590106

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

391 : 1, 17, 23, 391

458 : 1, 2, 229, 458

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 697,391,391,458, is 1.

Now, the common factors can be found like this.

697:17x 41

391:17x 23

391:17x 23

458:2x 229

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 23 = 6647

Therefore, the value for common factors is 6647.

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 = 48803590106/(1x6647)

LCM = 48803590106/6647

LCM = 7342198

Thus, we can understand that the LCM of 697,391,391,458 is 7342198.
