Given numbers are 697,451,521,164

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

The LCM of 697,451,521,164 is 15978028.

Find LCM of 697,451,521,164 with Prime Factorization

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

41 x 17 x 11 x 521 x 4 = 15978028

Therefore, the lowest common multiple of 697,451,521,164 is 15978028.

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 451 x 521 x 164 = 26859065068

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

451 : 1, 11, 41, 451

521 : 1, 521

164 : 1, 2, 4, 41, 82, 164

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 697,451,521,164, is 1.

Now, the common factors can be found like this.

697:17x 41

451:11x 41

521:521

164:2x 2x 41

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

41x 41 = 1681

Therefore, the value for common factors is 1681.

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 = 26859065068/(1x1681)

LCM = 26859065068/1681

LCM = 15978028

Thus, we can understand that the LCM of 697,451,521,164 is 15978028.
