Given numbers are 122,193,169,280

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

The LCM of 122,193,169,280 is 557098360.

Find LCM of 122,193,169,280 with Prime Factorization

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

2 x 61 x 193 x 169 x 140 = 557098360

Therefore, the lowest common multiple of 122,193,169,280 is 557098360.

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.

122 x 193 x 169 x 280 = 1114196720

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.

122 : 1, 2, 61, 122

193 : 1, 193

169 : 1, 13, 169

280 : 1, 2, 4, 5, 7, 8, 10, 14, 20, 28, 35, 40, 56, 70, 140, 280

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 122,193,169,280, is 1.

Now, the common factors can be found like this.

122:2x 61

193:193

169:13x 13

280:2x 2x 2x 5x 7

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 = 1114196720/(1x2)

LCM = 1114196720/2

LCM = 557098360

Thus, we can understand that the LCM of 122,193,169,280 is 557098360.
