Given numbers are 890,133,168,389

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

The LCM of 890,133,168,389 is 552551160.

Find LCM of 890,133,168,389 with Prime Factorization

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

2 x 7 x 445 x 19 x 12 x 389 = 552551160

Therefore, the lowest common multiple of 890,133,168,389 is 552551160.

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.

890 x 133 x 168 x 389 = 7735716240

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.

890 : 1, 2, 5, 10, 89, 178, 445, 890

133 : 1, 7, 19, 133

168 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 21, 24, 28, 42, 56, 84, 168

389 : 1, 389

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 890,133,168,389, is 1.

Now, the common factors can be found like this.

890:2x 5x 89

133:7x 19

168:2x 2x 2x 3x 7

389:389

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

2x 7 = 14

Therefore, the value for common factors is 14.

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 = 7735716240/(1x14)

LCM = 7735716240/14

LCM = 552551160

Thus, we can understand that the LCM of 890,133,168,389 is 552551160.
