Given numbers are 862,138,511,140

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

The LCM of 862,138,511,140 is 303932580.

Find LCM of 862,138,511,140 with Prime Factorization

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

2 x 7 x 431 x 69 x 73 x 10 = 303932580

Therefore, the lowest common multiple of 862,138,511,140 is 303932580.

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.

862 x 138 x 511 x 140 = 8510112240

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.

862 : 1, 2, 431, 862

138 : 1, 2, 3, 6, 23, 46, 69, 138

511 : 1, 7, 73, 511

140 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 70, 140

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 862,138,511,140, is 1.

Now, the common factors can be found like this.

862:2x 431

138:2x 3x 23

511:7x 73

140:2x 2x 5x 7

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

2x 2x 7 = 28

Therefore, the value for common factors is 28.

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 = 8510112240/(1x28)

LCM = 8510112240/28

LCM = 303932580

Thus, we can understand that the LCM of 862,138,511,140 is 303932580.
