Given numbers are 169,178,202,990

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

The LCM of 169,178,202,990 is 1503949590.

Find LCM of 169,178,202,990 with Prime Factorization

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

2 x 169 x 89 x 101 x 495 = 1503949590

Therefore, the lowest common multiple of 169,178,202,990 is 1503949590.

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.

169 x 178 x 202 x 990 = 6015798360

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.

169 : 1, 13, 169

178 : 1, 2, 89, 178

202 : 1, 2, 101, 202

990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 169,178,202,990, is 1.

Now, the common factors can be found like this.

169:13x 13

178:2x 89

202:2x 101

990:2x 3x 3x 5x 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 2 = 4

Therefore, the value for common factors is 4.

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 = 6015798360/(1x4)

LCM = 6015798360/4

LCM = 1503949590

Thus, we can understand that the LCM of 169,178,202,990 is 1503949590.
