Given numbers are 307,295,445,420

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

The LCM of 307,295,445,420 is 677063940.

Find LCM of 307,295,445,420 with Prime Factorization

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

5 x 307 x 59 x 89 x 84 = 677063940

Therefore, the lowest common multiple of 307,295,445,420 is 677063940.

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.

307 x 295 x 445 x 420 = 16926598500

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.

307 : 1, 307

295 : 1, 5, 59, 295

445 : 1, 5, 89, 445

420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 307,295,445,420, is 1.

Now, the common factors can be found like this.

307:307

295:5x 59

445:5x 89

420:2x 2x 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.

5x 5 = 25

Therefore, the value for common factors is 25.

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 = 16926598500/(1x25)

LCM = 16926598500/25

LCM = 677063940

Thus, we can understand that the LCM of 307,295,445,420 is 677063940.
