Given numbers are 905,398,488,742

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

The LCM of 905,398,488,742 is 32605839560.

Find LCM of 905,398,488,742 with Prime Factorization

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

2 x 905 x 199 x 244 x 371 = 32605839560

Therefore, the lowest common multiple of 905,398,488,742 is 32605839560.

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.

905 x 398 x 488 x 742 = 130423358240

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.

905 : 1, 5, 181, 905

398 : 1, 2, 199, 398

488 : 1, 2, 4, 8, 61, 122, 244, 488

742 : 1, 2, 7, 14, 53, 106, 371, 742

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 905,398,488,742, is 1.

Now, the common factors can be found like this.

905:5x 181

398:2x 199

488:2x 2x 2x 61

742:2x 7x 53

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 = 130423358240/(1x4)

LCM = 130423358240/4

LCM = 32605839560

Thus, we can understand that the LCM of 905,398,488,742 is 32605839560.
