Given numbers are 862,868,991,161

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

The LCM of 862,868,991,161 is 8527043644.

Find LCM of 862,868,991,161 with Prime Factorization

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

2 x 7 x 431 x 62 x 991 x 23 = 8527043644

Therefore, the lowest common multiple of 862,868,991,161 is 8527043644.

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 868 x 991 x 161 = 119378611016

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

868 : 1, 2, 4, 7, 14, 28, 31, 62, 124, 217, 434, 868

991 : 1, 991

161 : 1, 7, 23, 161

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 862,868,991,161, is 1.

Now, the common factors can be found like this.

862:2x 431

868:2x 2x 7x 31

991:991

161:7x 23

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 = 119378611016/(1x14)

LCM = 119378611016/14

LCM = 8527043644

Thus, we can understand that the LCM of 862,868,991,161 is 8527043644.
