Given numbers are 394,445,817,630

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

The LCM of 394,445,817,630 is 9024410430.

Find LCM of 394,445,817,630 with Prime Factorization

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

2 x 5 x 197 x 89 x 817 x 63 = 9024410430

Therefore, the lowest common multiple of 394,445,817,630 is 9024410430.

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.

394 x 445 x 817 x 630 = 90244104300

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.

394 : 1, 2, 197, 394

445 : 1, 5, 89, 445

817 : 1, 19, 43, 817

630 : 1, 2, 3, 5, 6, 7, 9, 10, 14, 15, 18, 21, 30, 35, 42, 45, 63, 70, 90, 105, 126, 210, 315, 630

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 394,445,817,630, is 1.

Now, the common factors can be found like this.

394:2x 197

445:5x 89

817:19x 43

630:2x 3x 3x 5x 7

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

2x 5 = 10

Therefore, the value for common factors is 10.

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 = 90244104300/(1x10)

LCM = 90244104300/10

LCM = 9024410430

Thus, we can understand that the LCM of 394,445,817,630 is 9024410430.
