Given numbers are 921,917,771,771

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

The LCM of 921,917,771,771 is 217051149.

Find LCM of 921,917,771,771 with Prime Factorization

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

3 x 257 x 307 x 917 x 1 x 1 = 217051149

Therefore, the lowest common multiple of 921,917,771,771 is 217051149.

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.

921 x 917 x 771 x 771 = 502039307637

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.

921 : 1, 3, 307, 921

917 : 1, 7, 131, 917

771 : 1, 3, 257, 771

771 : 1, 3, 257, 771

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 921,917,771,771, is 1.

Now, the common factors can be found like this.

921:3x 307

917:7x 131

771:3x 257

771:3x 257

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

3x 3x 257 = 2313

Therefore, the value for common factors is 2313.

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 = 502039307637/(1x2313)

LCM = 502039307637/2313

LCM = 217051149

Thus, we can understand that the LCM of 921,917,771,771 is 217051149.
