Given numbers are 681,364,403,197

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

The LCM of 681,364,403,197 is 1513827588.

Find LCM of 681,364,403,197 with Prime Factorization

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

13 x 681 x 28 x 31 x 197 = 1513827588

Therefore, the lowest common multiple of 681,364,403,197 is 1513827588.

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.

681 x 364 x 403 x 197 = 19679758644

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.

681 : 1, 3, 227, 681

364 : 1, 2, 4, 7, 13, 14, 26, 28, 52, 91, 182, 364

403 : 1, 13, 31, 403

197 : 1, 197

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 681,364,403,197, is 1.

Now, the common factors can be found like this.

681:3x 227

364:2x 2x 7x 13

403:13x 31

197:197

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

13 = 13

Therefore, the value for common factors is 13.

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 = 19679758644/(1x13)

LCM = 19679758644/13

LCM = 1513827588

Thus, we can understand that the LCM of 681,364,403,197 is 1513827588.
