Given numbers are 245,296,163,990

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

The LCM of 245,296,163,990 is 1170255240.

Find LCM of 245,296,163,990 with Prime Factorization

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

2 x 5 x 49 x 148 x 163 x 99 = 1170255240

Therefore, the lowest common multiple of 245,296,163,990 is 1170255240.

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.

245 x 296 x 163 x 990 = 11702552400

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.

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

296 : 1, 2, 4, 8, 37, 74, 148, 296

163 : 1, 163

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 245,296,163,990, is 1.

Now, the common factors can be found like this.

245:5x 7x 7

296:2x 2x 2x 37

163:163

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 5 = 10

Therefore, the value for common factors is 10.

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 = 11702552400/(1x10)

LCM = 11702552400/10

LCM = 1170255240

Thus, we can understand that the LCM of 245,296,163,990 is 1170255240.
