Calculate the LCM of 989,330,770,289

Given numbers are 989,330,770,289

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

The LCM of 989,330,770,289 is 660246510.

Find LCM of 989,330,770,289 with Prime Factorization


2 989, 330, 770, 289
5 989, 165, 385, 289
11 989, 33, 77, 289
989, 3, 7, 289

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

2 x 5 x 11 x 989 x 3 x 7 x 289 = 660246510

Therefore, the lowest common multiple of 989,330,770,289 is 660246510.

LCM Formula to Find Lowest Common Multiple of 989,330,770,289

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.

989 x 330 x 770 x 289 = 72627116100

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.

989 : 1, 23, 43, 989

330 : 1, 2, 3, 5, 6, 10, 11, 15, 22, 30, 33, 55, 66, 110, 165, 330

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

289 : 1, 17, 289

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 989,330,770,289, is 1.

Now, the common factors can be found like this.

989:23x 43

330:2x 3x 5x 11

770:2x 5x 7x 11

289:17x 17

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

2x 5x 11 = 110

Therefore, the value for common factors is 110.

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 = 72627116100/(1x110)

LCM = 72627116100/110

LCM = 660246510

Thus, we can understand that the LCM of 989,330,770,289 is 660246510.
