Given numbers are 727,847,781,639

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

The LCM of 727,847,781,639 is 393476391.

Find LCM of 727,847,781,639 with Prime Factorization

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

11 x 71 x 727 x 77 x 1 x 9 = 393476391

Therefore, the lowest common multiple of 727,847,781,639 is 393476391.

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.

727 x 847 x 781 x 639 = 307305061371

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.

727 : 1, 727

847 : 1, 7, 11, 77, 121, 847

781 : 1, 11, 71, 781

639 : 1, 3, 9, 71, 213, 639

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 727,847,781,639, is 1.

Now, the common factors can be found like this.

727:727

847:7x 11x 11

781:11x 71

639:3x 3x 71

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

11x 71 = 781

Therefore, the value for common factors is 781.

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 = 307305061371/(1x781)

LCM = 307305061371/781

LCM = 393476391

Thus, we can understand that the LCM of 727,847,781,639 is 393476391.
