Given numbers are 920,760,772,660

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

The LCM of 920,760,772,660 is 111330120.

Find LCM of 920,760,772,660 with Prime Factorization

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

2 x 2 x 2 x 5 x 23 x 19 x 193 x 33 = 111330120

Therefore, the lowest common multiple of 920,760,772,660 is 111330120.

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.

920 x 760 x 772 x 660 = 356256384000

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.

920 : 1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920

760 : 1, 2, 4, 5, 8, 10, 19, 20, 38, 40, 76, 95, 152, 190, 380, 760

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

660 : 1, 2, 3, 4, 5, 6, 10, 11, 12, 15, 20, 22, 30, 33, 44, 55, 60, 66, 110, 132, 165, 220, 330, 660

4 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 920,760,772,660, is 4.

Now, the common factors can be found like this.

920:2x 2x 2x 5x 23

760:2x 2x 2x 5x 19

772:2x 2x 193

660:2x 2x 3x 5x 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 2x 2x 5x 5 = 800

Therefore, the value for common factors is 800.

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 = 356256384000/(4x800)

LCM = 356256384000/3200

LCM = 111330120

Thus, we can understand that the LCM of 920,760,772,660 is 111330120.
