Given numbers are 166,221,163,690

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

The LCM of 166,221,163,690 is 2063037210.

Find LCM of 166,221,163,690 with Prime Factorization

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

2 x 83 x 221 x 163 x 345 = 2063037210

Therefore, the lowest common multiple of 166,221,163,690 is 2063037210.

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.

166 x 221 x 163 x 690 = 4126074420

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.

166 : 1, 2, 83, 166

221 : 1, 13, 17, 221

163 : 1, 163

690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 166,221,163,690, is 1.

Now, the common factors can be found like this.

166:2x 83

221:13x 17

163:163

690:2x 3x 5x 23

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 = 4126074420/(1x2)

LCM = 4126074420/2

LCM = 2063037210

Thus, we can understand that the LCM of 166,221,163,690 is 2063037210.
