Given numbers are 660,744,289,770

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

The LCM of 660,744,289,770 is 82781160.

Find LCM of 660,744,289,770 with Prime Factorization

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

2 x 2 x 3 x 5 x 11 x 1 x 62 x 289 x 7 = 82781160

Therefore, the lowest common multiple of 660,744,289,770 is 82781160.

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.

660 x 744 x 289 x 770 = 109271131200

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.

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

744 : 1, 2, 3, 4, 6, 8, 12, 24, 31, 62, 93, 124, 186, 248, 372, 744

289 : 1, 17, 289

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 660,744,289,770, is 1.

Now, the common factors can be found like this.

660:2x 2x 3x 5x 11

744:2x 2x 2x 3x 31

289:17x 17

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 3x 5x 11 = 1320

Therefore, the value for common factors is 1320.

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 = 109271131200/(1x1320)

LCM = 109271131200/1320

LCM = 82781160

Thus, we can understand that the LCM of 660,744,289,770 is 82781160.
