Given numbers are 245,706,704,990

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

The LCM of 245,706,704,990 is 547968960.

Find LCM of 245,706,704,990 with Prime Factorization

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

2 x 5 x 11 x 49 x 353 x 32 x 9 = 547968960

Therefore, the lowest common multiple of 245,706,704,990 is 547968960.

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 706 x 704 x 990 = 120553171200

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

706 : 1, 2, 353, 706

704 : 1, 2, 4, 8, 11, 16, 22, 32, 44, 64, 88, 176, 352, 704

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 245,706,704,990, is 1.

Now, the common factors can be found like this.

245:5x 7x 7

706:2x 353

704:2x 2x 2x 2x 2x 2x 11

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 2x 5x 11 = 220

Therefore, the value for common factors is 220.

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 = 120553171200/(1x220)

LCM = 120553171200/220

LCM = 547968960

Thus, we can understand that the LCM of 245,706,704,990 is 547968960.
