Given numbers are 242,438,658,785

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

The LCM of 242,438,658,785 is 13687528470.

Find LCM of 242,438,658,785 with Prime Factorization

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

2 x 121 x 219 x 329 x 785 = 13687528470

Therefore, the lowest common multiple of 242,438,658,785 is 13687528470.

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.

242 x 438 x 658 x 785 = 54750113880

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.

242 : 1, 2, 11, 22, 121, 242

438 : 1, 2, 3, 6, 73, 146, 219, 438

658 : 1, 2, 7, 14, 47, 94, 329, 658

785 : 1, 5, 157, 785

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 242,438,658,785, is 1.

Now, the common factors can be found like this.

242:2x 11x 11

438:2x 3x 73

658:2x 7x 47

785:5x 157

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 = 54750113880/(1x4)

LCM = 54750113880/4

LCM = 13687528470

Thus, we can understand that the LCM of 242,438,658,785 is 13687528470.
