Given numbers are 781,221,874,161,966

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

The LCM of 781,221,874,161,966 is 3167918754.

Find LCM of 781,221,874,161,966 with Prime Factorization

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

2 x 7 x 23 x 781 x 221 x 19 x 1 x 3 = 3167918754

Therefore, the lowest common multiple of 781,221,874,161,966 is 3167918754.

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.

781 x 221 x 874 x 161 x 966 = 23461606292124

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.

781 : 1, 11, 71, 781

221 : 1, 13, 17, 221

874 : 1, 2, 19, 23, 38, 46, 437, 874

161 : 1, 7, 23, 161

966 : 1, 2, 3, 6, 7, 14, 21, 23, 42, 46, 69, 138, 161, 322, 483, 966

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 781,221,874,161,966, is 1.

Now, the common factors can be found like this.

781:11x 71

221:13x 17

874:2x 19x 23

161:7x 23

966:2x 3x 7x 23

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

2x 7x 23x 23 = 7406

Therefore, the value for common factors is 7406.

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 = 23461606292124/(1x7406)

LCM = 23461606292124/7406

LCM = 3167918754

Thus, we can understand that the LCM of 781,221,874,161,966 is 3167918754.
