Given numbers are 921,818,889,409

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

The LCM of 921,818,889,409 is 669753042.

Find LCM of 921,818,889,409 with Prime Factorization

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

409 x 921 x 2 x 889 x 1 = 669753042

Therefore, the lowest common multiple of 921,818,889,409 is 669753042.

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 818 x 889 x 409 = 273928994178

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

818 : 1, 2, 409, 818

889 : 1, 7, 127, 889

409 : 1, 409

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 921,818,889,409, is 1.

Now, the common factors can be found like this.

921:3x 307

818:2x 409

889:7x 127

409:409

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

409 = 409

Therefore, the value for common factors is 409.

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 = 273928994178/(1x409)

LCM = 273928994178/409

LCM = 669753042

Thus, we can understand that the LCM of 921,818,889,409 is 669753042.
