Given numbers are 169,221,643,741

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

The LCM of 169,221,643,741 is 105298323.

Find LCM of 169,221,643,741 with Prime Factorization

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

13 x 13 x 17 x 643 x 57 = 105298323

Therefore, the lowest common multiple of 169,221,643,741 is 105298323.

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.

169 x 221 x 643 x 741 = 17795416587

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.

169 : 1, 13, 169

221 : 1, 13, 17, 221

643 : 1, 643

741 : 1, 3, 13, 19, 39, 57, 247, 741

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 169,221,643,741, is 1.

Now, the common factors can be found like this.

169:13x 13

221:13x 17

643:643

741:3x 13x 19

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

13x 13 = 169

Therefore, the value for common factors is 169.

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 = 17795416587/(1x169)

LCM = 17795416587/169

LCM = 105298323

Thus, we can understand that the LCM of 169,221,643,741 is 105298323.
