Given numbers are 910,991,921,538

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

The LCM of 910,991,921,538 is 223422525690.

Find LCM of 910,991,921,538 with Prime Factorization

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

2 x 455 x 991 x 921 x 269 = 223422525690

Therefore, the lowest common multiple of 910,991,921,538 is 223422525690.

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.

910 x 991 x 921 x 538 = 446845051380

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.

910 : 1, 2, 5, 7, 10, 13, 14, 26, 35, 65, 70, 91, 130, 182, 455, 910

991 : 1, 991

921 : 1, 3, 307, 921

538 : 1, 2, 269, 538

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 910,991,921,538, is 1.

Now, the common factors can be found like this.

910:2x 5x 7x 13

991:991

921:3x 307

538:2x 269

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 = 446845051380/(1x2)

LCM = 446845051380/2

LCM = 223422525690

Thus, we can understand that the LCM of 910,991,921,538 is 223422525690.
