Given numbers are 620,248,775,395

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

The LCM of 620,248,775,395 is 489800.

Find LCM of 620,248,775,395 with Prime Factorization

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

2 x 2 x 5 x 31 x 1 x 2 x 5 x 79 = 489800

Therefore, the lowest common multiple of 620,248,775,395 is 489800.

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.

620 x 248 x 775 x 395 = 47069780000

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.

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

248 : 1, 2, 4, 8, 31, 62, 124, 248

775 : 1, 5, 25, 31, 155, 775

395 : 1, 5, 79, 395

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 620,248,775,395, is 1.

Now, the common factors can be found like this.

620:2x 2x 5x 31

248:2x 2x 2x 31

775:5x 5x 31

395:5x 79

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 5x 5x 31x 31 = 96100

Therefore, the value for common factors is 96100.

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 = 47069780000/(1x96100)

LCM = 47069780000/96100

LCM = 489800

Thus, we can understand that the LCM of 620,248,775,395 is 489800.
