Calculate the LCM of 989,105,346,438

Given numbers are 989,105,346,438

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

The LCM of 989,105,346,438 is 2622917010.

Find LCM of 989,105,346,438 with Prime Factorization


2 989, 105, 346, 438
3 989, 105, 173, 219
989, 35, 173, 73

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

2 x 3 x 989 x 35 x 173 x 73 = 2622917010

Therefore, the lowest common multiple of 989,105,346,438 is 2622917010.

LCM Formula to Find Lowest Common Multiple of 989,105,346,438

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 105 x 346 x 438 = 15737502060

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

105 : 1, 3, 5, 7, 15, 21, 35, 105

346 : 1, 2, 173, 346

438 : 1, 2, 3, 6, 73, 146, 219, 438

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 989,105,346,438, is 1.

Now, the common factors can be found like this.

989:23x 43

105:3x 5x 7

346:2x 173

438:2x 3x 73

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

2x 3 = 6

Therefore, the value for common factors is 6.

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 = 15737502060/(1x6)

LCM = 15737502060/6

LCM = 2622917010

Thus, we can understand that the LCM of 989,105,346,438 is 2622917010.
