Given numbers are 273,638,221,953

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

The LCM of 273,638,221,953 is 2821792974.

Find LCM of 273,638,221,953 with Prime Factorization

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

13 x 21 x 638 x 17 x 953 = 2821792974

Therefore, the lowest common multiple of 273,638,221,953 is 2821792974.

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.

273 x 638 x 221 x 953 = 36683308662

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.

273 : 1, 3, 7, 13, 21, 39, 91, 273

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

221 : 1, 13, 17, 221

953 : 1, 953

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 273,638,221,953, is 1.

Now, the common factors can be found like this.

273:3x 7x 13

638:2x 11x 29

221:13x 17

953:953

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 = 36683308662/(1x13)

LCM = 36683308662/13

LCM = 2821792974

Thus, we can understand that the LCM of 273,638,221,953 is 2821792974.
