Given numbers are 862,728,989

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

The LCM of 862,728,989 is 310316552.

Find LCM of 862,728,989 with Prime Factorization

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

2 x 431 x 364 x 989 = 310316552

Therefore, the lowest common multiple of 862,728,989 is 310316552.

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 728 x 989 = 620633104

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

728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728

989 : 1, 23, 43, 989

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 862,728,989, is 1.

Now, the common factors can be found like this.

862:2x 431

728:2x 2x 2x 7x 13

989:23x 43

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

2 = 2

Therefore, the value for common factors is 2.

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 = 620633104/(1x2)

LCM = 620633104/2

LCM = 310316552

Thus, we can understand that the LCM of 862,728,989 is 310316552.
