Given numbers are 421,845,247,274

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

The LCM of 421,845,247,274 is 1852008470.

Find LCM of 421,845,247,274 with Prime Factorization

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

13 x 421 x 65 x 19 x 274 = 1852008470

Therefore, the lowest common multiple of 421,845,247,274 is 1852008470.

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.

421 x 845 x 247 x 274 = 24076110110

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.

421 : 1, 421

845 : 1, 5, 13, 65, 169, 845

247 : 1, 13, 19, 247

274 : 1, 2, 137, 274

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 421,845,247,274, is 1.

Now, the common factors can be found like this.

421:421

845:5x 13x 13

247:13x 19

274:2x 137

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 = 24076110110/(1x13)

LCM = 24076110110/13

LCM = 1852008470

Thus, we can understand that the LCM of 421,845,247,274 is 1852008470.
