Given numbers are 847,480,975,705

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

The LCM of 847,480,975,705 is 1242040800.

Find LCM of 847,480,975,705 with Prime Factorization

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

3 x 5 x 847 x 32 x 65 x 47 = 1242040800

Therefore, the lowest common multiple of 847,480,975,705 is 1242040800.

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.

847 x 480 x 975 x 705 = 279459180000

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.

847 : 1, 7, 11, 77, 121, 847

480 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 32, 40, 48, 60, 80, 96, 120, 160, 240, 480

975 : 1, 3, 5, 13, 15, 25, 39, 65, 75, 195, 325, 975

705 : 1, 3, 5, 15, 47, 141, 235, 705

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 847,480,975,705, is 1.

Now, the common factors can be found like this.

847:7x 11x 11

480:2x 2x 2x 2x 2x 3x 5

975:3x 5x 5x 13

705:3x 5x 47

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

3x 3x 5x 5 = 225

Therefore, the value for common factors is 225.

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 = 279459180000/(1x225)

LCM = 279459180000/225

LCM = 1242040800

Thus, we can understand that the LCM of 847,480,975,705 is 1242040800.
