Given numbers are 638,611,247,243

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

The LCM of 638,611,247,243 is 1799789706.

Find LCM of 638,611,247,243 with Prime Factorization

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

13 x 638 x 47 x 19 x 243 = 1799789706

Therefore, the lowest common multiple of 638,611,247,243 is 1799789706.

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 611 x 247 x 243 = 23397266178

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

611 : 1, 13, 47, 611

247 : 1, 13, 19, 247

243 : 1, 3, 9, 27, 81, 243

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 638,611,247,243, is 1.

Now, the common factors can be found like this.

638:2x 11x 29

611:13x 47

247:13x 19

243:3x 3x 3x 3x 3

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

13 = 13

Therefore, the value for common factors is 13.

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 = 23397266178/(1x13)

LCM = 23397266178/13

LCM = 1799789706

Thus, we can understand that the LCM of 638,611,247,243 is 1799789706.
