Given numbers are 851,203,340,990

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

The LCM of 851,203,340,990 is 5814865980.

Find LCM of 851,203,340,990 with Prime Factorization

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

2 x 5 x 851 x 203 x 34 x 99 = 5814865980

Therefore, the lowest common multiple of 851,203,340,990 is 5814865980.

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.

851 x 203 x 340 x 990 = 58148659800

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.

851 : 1, 23, 37, 851

203 : 1, 7, 29, 203

340 : 1, 2, 4, 5, 10, 17, 20, 34, 68, 85, 170, 340

990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 851,203,340,990, is 1.

Now, the common factors can be found like this.

851:23x 37

203:7x 29

340:2x 2x 5x 17

990:2x 3x 3x 5x 11

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

2x 5 = 10

Therefore, the value for common factors is 10.

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 = 58148659800/(1x10)

LCM = 58148659800/10

LCM = 5814865980

Thus, we can understand that the LCM of 851,203,340,990 is 5814865980.
