Given numbers are 646,869,921,176

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

The LCM of 646,869,921,176 is 4136203632.

Find LCM of 646,869,921,176 with Prime Factorization

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

2 x 11 x 323 x 79 x 921 x 8 = 4136203632

Therefore, the lowest common multiple of 646,869,921,176 is 4136203632.

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.

646 x 869 x 921 x 176 = 90996479904

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.

646 : 1, 2, 17, 19, 34, 38, 323, 646

869 : 1, 11, 79, 869

921 : 1, 3, 307, 921

176 : 1, 2, 4, 8, 11, 16, 22, 44, 88, 176

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 646,869,921,176, is 1.

Now, the common factors can be found like this.

646:2x 17x 19

869:11x 79

921:3x 307

176:2x 2x 2x 2x 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 11 = 22

Therefore, the value for common factors is 22.

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 = 90996479904/(1x22)

LCM = 90996479904/22

LCM = 4136203632

Thus, we can understand that the LCM of 646,869,921,176 is 4136203632.
