Calculate the LCM of 161,641,645,978,349

Given numbers are 161,641,645,978,349

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

The LCM of 161,641,645,978,349 is 7573325920230.

Find LCM of 161,641,645,978,349 with Prime Factorization


3 161, 641, 645, 978, 349
161, 641, 215, 326, 349

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

3 x 161 x 641 x 215 x 326 x 349 = 7573325920230

Therefore, the lowest common multiple of 161,641,645,978,349 is 7573325920230.

LCM Formula to Find Lowest Common Multiple of 161,641,645,978,349

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.

161 x 641 x 645 x 978 x 349 = 22719977760690

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.

161 : 1, 7, 23, 161

641 : 1, 641

645 : 1, 3, 5, 15, 43, 129, 215, 645

978 : 1, 2, 3, 6, 163, 326, 489, 978

349 : 1, 349

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 161,641,645,978,349, is 1.

Now, the common factors can be found like this.

161:7x 23

641:641

645:3x 5x 43

978:2x 3x 163

349:349

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

3 = 3

Therefore, the value for common factors is 3.

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 = 22719977760690/(1x3)

LCM = 22719977760690/3

LCM = 7573325920230

Thus, we can understand that the LCM of 161,641,645,978,349 is 7573325920230.
