Given numbers are 997,515,721,284

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

The LCM of 997,515,721,284 is 1020748540.

Find LCM of 997,515,721,284 with Prime Factorization

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

103 x 997 x 5 x 7 x 284 = 1020748540

Therefore, the lowest common multiple of 997,515,721,284 is 1020748540.

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.

997 x 515 x 721 x 284 = 105137099620

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.

997 : 1, 997

515 : 1, 5, 103, 515

721 : 1, 7, 103, 721

284 : 1, 2, 4, 71, 142, 284

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 997,515,721,284, is 1.

Now, the common factors can be found like this.

997:997

515:5x 103

721:7x 103

284:2x 2x 71

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

103 = 103

Therefore, the value for common factors is 103.

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 = 105137099620/(1x103)

LCM = 105137099620/103

LCM = 1020748540

Thus, we can understand that the LCM of 997,515,721,284 is 1020748540.
