Given numbers are 122,422,245,225,220

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

The LCM of 122,422,245,225,220 is 6243722100.

Find LCM of 122,422,245,225,220 with Prime Factorization

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

2 x 5 x 61 x 211 x 49 x 45 x 22 = 6243722100

Therefore, the lowest common multiple of 122,422,245,225,220 is 6243722100.

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 422 x 245 x 225 x 220 = 624372210000

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

422 : 1, 2, 211, 422

245 : 1, 5, 7, 35, 49, 245

225 : 1, 3, 5, 9, 15, 25, 45, 75, 225

220 : 1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, 220

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 122,422,245,225,220, is 1.

Now, the common factors can be found like this.

122:2x 61

422:2x 211

245:5x 7x 7

225:3x 3x 5x 5

220:2x 2x 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 2x 5x 5 = 100

Therefore, the value for common factors is 100.

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 = 624372210000/(1x100)

LCM = 624372210000/100

LCM = 6243722100

Thus, we can understand that the LCM of 122,422,245,225,220 is 6243722100.
