Given numbers are 971,538,390,919

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

The LCM of 971,538,390,919 is 93616333590.

Find LCM of 971,538,390,919 with Prime Factorization

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

2 x 971 x 269 x 195 x 919 = 93616333590

Therefore, the lowest common multiple of 971,538,390,919 is 93616333590.

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.

971 x 538 x 390 x 919 = 187232667180

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.

971 : 1, 971

538 : 1, 2, 269, 538

390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390

919 : 1, 919

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 971,538,390,919, is 1.

Now, the common factors can be found like this.

971:971

538:2x 269

390:2x 3x 5x 13

919:919

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

2 = 2

Therefore, the value for common factors is 2.

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 = 187232667180/(1x2)

LCM = 187232667180/2

LCM = 93616333590

Thus, we can understand that the LCM of 971,538,390,919 is 93616333590.
