Given numbers are 821,867,737,921

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

The LCM of 821,867,737,921 is 161052740013.

Find LCM of 821,867,737,921 with Prime Factorization

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

3 x 821 x 289 x 737 x 307 = 161052740013

Therefore, the lowest common multiple of 821,867,737,921 is 161052740013.

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.

821 x 867 x 737 x 921 = 483158220039

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.

821 : 1, 821

867 : 1, 3, 17, 51, 289, 867

737 : 1, 11, 67, 737

921 : 1, 3, 307, 921

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 821,867,737,921, is 1.

Now, the common factors can be found like this.

821:821

867:3x 17x 17

737:11x 67

921:3x 307

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

3 = 3

Therefore, the value for common factors is 3.

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 = 483158220039/(1x3)

LCM = 483158220039/3

LCM = 161052740013

Thus, we can understand that the LCM of 821,867,737,921 is 161052740013.
