Given numbers are 221,190,969,742

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

The LCM of 221,190,969,742 is 46734870.

Find LCM of 221,190,969,742 with Prime Factorization

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

2 x 17 x 19 x 13 x 5 x 3 x 371 = 46734870

Therefore, the lowest common multiple of 221,190,969,742 is 46734870.

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.

221 x 190 x 969 x 742 = 30190726020

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.

221 : 1, 13, 17, 221

190 : 1, 2, 5, 10, 19, 38, 95, 190

969 : 1, 3, 17, 19, 51, 57, 323, 969

742 : 1, 2, 7, 14, 53, 106, 371, 742

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 221,190,969,742, is 1.

Now, the common factors can be found like this.

221:13x 17

190:2x 5x 19

969:3x 17x 19

742:2x 7x 53

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

2x 17x 19 = 646

Therefore, the value for common factors is 646.

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 = 30190726020/(1x646)

LCM = 30190726020/646

LCM = 46734870

Thus, we can understand that the LCM of 221,190,969,742 is 46734870.
