Given numbers are 126,161,442,164

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

The LCM of 126,161,442,164 is 52517556.

Find LCM of 126,161,442,164 with Prime Factorization

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

2 x 7 x 9 x 23 x 221 x 82 = 52517556

Therefore, the lowest common multiple of 126,161,442,164 is 52517556.

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.

126 x 161 x 442 x 164 = 1470491568

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.

126 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 42, 63, 126

161 : 1, 7, 23, 161

442 : 1, 2, 13, 17, 26, 34, 221, 442

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 126,161,442,164, is 1.

Now, the common factors can be found like this.

126:2x 3x 3x 7

161:7x 23

442:2x 13x 17

164:2x 2x 41

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

2x 2x 7 = 28

Therefore, the value for common factors is 28.

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 = 1470491568/(1x28)

LCM = 1470491568/28

LCM = 52517556

Thus, we can understand that the LCM of 126,161,442,164 is 52517556.
