Given numbers are 403,688,351,431

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

The LCM of 403,688,351,431 is 3226521168.

Find LCM of 403,688,351,431 with Prime Factorization

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

13 x 31 x 688 x 27 x 431 = 3226521168

Therefore, the lowest common multiple of 403,688,351,431 is 3226521168.

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.

403 x 688 x 351 x 431 = 41944775184

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.

403 : 1, 13, 31, 403

688 : 1, 2, 4, 8, 16, 43, 86, 172, 344, 688

351 : 1, 3, 9, 13, 27, 39, 117, 351

431 : 1, 431

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 403,688,351,431, is 1.

Now, the common factors can be found like this.

403:13x 31

688:2x 2x 2x 2x 43

351:3x 3x 3x 13

431:431

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

13 = 13

Therefore, the value for common factors is 13.

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 = 41944775184/(1x13)

LCM = 41944775184/13

LCM = 3226521168

Thus, we can understand that the LCM of 403,688,351,431 is 3226521168.
