Given numbers are 462,221,331,781

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

The LCM of 462,221,331,781 is 2399499102.

Find LCM of 462,221,331,781 with Prime Factorization

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

11 x 42 x 221 x 331 x 71 = 2399499102

Therefore, the lowest common multiple of 462,221,331,781 is 2399499102.

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.

462 x 221 x 331 x 781 = 26394490122

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.

462 : 1, 2, 3, 6, 7, 11, 14, 21, 22, 33, 42, 66, 77, 154, 231, 462

221 : 1, 13, 17, 221

331 : 1, 331

781 : 1, 11, 71, 781

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 462,221,331,781, is 1.

Now, the common factors can be found like this.

462:2x 3x 7x 11

221:13x 17

331:331

781:11x 71

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

11 = 11

Therefore, the value for common factors is 11.

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 = 26394490122/(1x11)

LCM = 26394490122/11

LCM = 2399499102

Thus, we can understand that the LCM of 462,221,331,781 is 2399499102.
