Given numbers are 321,749,710,169

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

The LCM of 321,749,710,169 is 269617530.

Find LCM of 321,749,710,169 with Prime Factorization

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

107 x 3 x 7 x 710 x 169 = 269617530

Therefore, the lowest common multiple of 321,749,710,169 is 269617530.

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.

321 x 749 x 710 x 169 = 28849075710

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.

321 : 1, 3, 107, 321

749 : 1, 7, 107, 749

710 : 1, 2, 5, 10, 71, 142, 355, 710

169 : 1, 13, 169

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 321,749,710,169, is 1.

Now, the common factors can be found like this.

321:3x 107

749:7x 107

710:2x 5x 71

169:13x 13

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

107 = 107

Therefore, the value for common factors is 107.

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 = 28849075710/(1x107)

LCM = 28849075710/107

LCM = 269617530

Thus, we can understand that the LCM of 321,749,710,169 is 269617530.
