Given numbers are 282,354,421,620

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

The LCM of 282,354,421,620 is 2171425380.

Find LCM of 282,354,421,620 with Prime Factorization

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

2 x 3 x 47 x 59 x 421 x 310 = 2171425380

Therefore, the lowest common multiple of 282,354,421,620 is 2171425380.

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.

282 x 354 x 421 x 620 = 26057104560

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.

282 : 1, 2, 3, 6, 47, 94, 141, 282

354 : 1, 2, 3, 6, 59, 118, 177, 354

421 : 1, 421

620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 282,354,421,620, is 1.

Now, the common factors can be found like this.

282:2x 3x 47

354:2x 3x 59

421:421

620:2x 2x 5x 31

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

2x 2x 3 = 12

Therefore, the value for common factors is 12.

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 = 26057104560/(1x12)

LCM = 26057104560/12

LCM = 2171425380

Thus, we can understand that the LCM of 282,354,421,620 is 2171425380.
