Given numbers are 821,454,456,133

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

The LCM of 821,454,456,133 is 594883464.

Find LCM of 821,454,456,133 with Prime Factorization

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

2 x 19 x 821 x 227 x 12 x 7 = 594883464

Therefore, the lowest common multiple of 821,454,456,133 is 594883464.

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 454 x 456 x 133 = 22605571632

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

454 : 1, 2, 227, 454

456 : 1, 2, 3, 4, 6, 8, 12, 19, 24, 38, 57, 76, 114, 152, 228, 456

133 : 1, 7, 19, 133

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 821,454,456,133, is 1.

Now, the common factors can be found like this.

821:821

454:2x 227

456:2x 2x 2x 3x 19

133:7x 19

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

2x 19 = 38

Therefore, the value for common factors is 38.

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 = 22605571632/(1x38)

LCM = 22605571632/38

LCM = 594883464

Thus, we can understand that the LCM of 821,454,456,133 is 594883464.
