Given numbers are 661,999,781,215,703

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

The LCM of 661,999,781,215,703 is 2106735640515.

Find LCM of 661,999,781,215,703 with Prime Factorization

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

37 x 661 x 27 x 781 x 215 x 19 = 2106735640515

Therefore, the lowest common multiple of 661,999,781,215,703 is 2106735640515.

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.

661 x 999 x 781 x 215 x 703 = 77949218699055

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.

661 : 1, 661

999 : 1, 3, 9, 27, 37, 111, 333, 999

781 : 1, 11, 71, 781

215 : 1, 5, 43, 215

703 : 1, 19, 37, 703

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 661,999,781,215,703, is 1.

Now, the common factors can be found like this.

661:661

999:3x 3x 3x 37

781:11x 71

215:5x 43

703:19x 37

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

37 = 37

Therefore, the value for common factors is 37.

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 = 77949218699055/(1x37)

LCM = 77949218699055/37

LCM = 2106735640515

Thus, we can understand that the LCM of 661,999,781,215,703 is 2106735640515.
