Given numbers are 248,813,772,820

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

The LCM of 248,813,772,820 is 7977253560.

Find LCM of 248,813,772,820 with Prime Factorization

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

2 x 2 x 62 x 813 x 193 x 205 = 7977253560

Therefore, the lowest common multiple of 248,813,772,820 is 7977253560.

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.

248 x 813 x 772 x 820 = 127636056960

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.

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

813 : 1, 3, 271, 813

772 : 1, 2, 4, 193, 386, 772

820 : 1, 2, 4, 5, 10, 20, 41, 82, 164, 205, 410, 820

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 248,813,772,820, is 1.

Now, the common factors can be found like this.

248:2x 2x 2x 31

813:3x 271

772:2x 2x 193

820:2x 2x 5x 41

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 2x 2 = 16

Therefore, the value for common factors is 16.

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 = 127636056960/(1x16)

LCM = 127636056960/16

LCM = 7977253560

Thus, we can understand that the LCM of 248,813,772,820 is 7977253560.
