Given numbers are 921,164,986,889

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

The LCM of 921,164,986,889 is 66199111188.

Find LCM of 921,164,986,889 with Prime Factorization

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

2 x 921 x 82 x 493 x 889 = 66199111188

Therefore, the lowest common multiple of 921,164,986,889 is 66199111188.

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.

921 x 164 x 986 x 889 = 132398222376

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.

921 : 1, 3, 307, 921

164 : 1, 2, 4, 41, 82, 164

986 : 1, 2, 17, 29, 34, 58, 493, 986

889 : 1, 7, 127, 889

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 921,164,986,889, is 1.

Now, the common factors can be found like this.

921:3x 307

164:2x 2x 41

986:2x 17x 29

889:7x 127

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 = 132398222376/(1x2)

LCM = 132398222376/2

LCM = 66199111188

Thus, we can understand that the LCM of 921,164,986,889 is 66199111188.
