Given numbers are 638,562,178,232

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

The LCM of 638,562,178,232 is 63822968.

Find LCM of 638,562,178,232 with Prime Factorization

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

2 x 29 x 11 x 281 x 89 x 4 = 63822968

Therefore, the lowest common multiple of 638,562,178,232 is 63822968.

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.

638 x 562 x 178 x 232 = 14806928576

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.

638 : 1, 2, 11, 22, 29, 58, 319, 638

562 : 1, 2, 281, 562

178 : 1, 2, 89, 178

232 : 1, 2, 4, 8, 29, 58, 116, 232

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 638,562,178,232, is 2.

Now, the common factors can be found like this.

638:2x 11x 29

562:2x 281

178:2x 89

232:2x 2x 2x 29

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 29 = 116

Therefore, the value for common factors is 116.

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 = 14806928576/(2x116)

LCM = 14806928576/232

LCM = 63822968

Thus, we can understand that the LCM of 638,562,178,232 is 63822968.
