Given numbers are 772,908,990,770

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

The LCM of 772,908,990,770 is 607220460.

Find LCM of 772,908,990,770 with Prime Factorization

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

2 x 2 x 5 x 11 x 193 x 227 x 9 x 7 = 607220460

Therefore, the lowest common multiple of 772,908,990,770 is 607220460.

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.

772 x 908 x 990 x 770 = 534354004800

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.

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

908 : 1, 2, 4, 227, 454, 908

990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990

770 : 1, 2, 5, 7, 10, 11, 14, 22, 35, 55, 70, 77, 110, 154, 385, 770

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 772,908,990,770, is 2.

Now, the common factors can be found like this.

772:2x 2x 193

908:2x 2x 227

990:2x 3x 3x 5x 11

770:2x 5x 7x 11

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 5x 11 = 440

Therefore, the value for common factors is 440.

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 = 534354004800/(2x440)

LCM = 534354004800/880

LCM = 607220460

Thus, we can understand that the LCM of 772,908,990,770 is 607220460.
