Given numbers are 170,979,721,51

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

The LCM of 170,979,721,51 is 359988090.

Find LCM of 170,979,721,51 with Prime Factorization

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

17 x 10 x 979 x 721 x 3 = 359988090

Therefore, the lowest common multiple of 170,979,721,51 is 359988090.

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.

170 x 979 x 721 x 51 = 6119797530

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.

170 : 1, 2, 5, 10, 17, 34, 85, 170

979 : 1, 11, 89, 979

721 : 1, 7, 103, 721

51 : 1, 3, 17, 51

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 170,979,721,51, is 1.

Now, the common factors can be found like this.

170:2x 5x 17

979:11x 89

721:7x 103

51:3x 17

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

17 = 17

Therefore, the value for common factors is 17.

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 = 6119797530/(1x17)

LCM = 6119797530/17

LCM = 359988090

Thus, we can understand that the LCM of 170,979,721,51 is 359988090.
