Calculate the LCM of 297,380,644,436

Given numbers are 297,380,644,436

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

The LCM of 297,380,644,436 is 1980580140.

Find LCM of 297,380,644,436 with Prime Factorization


2 297, 380, 644, 436
2 297, 190, 322, 218
297, 95, 161, 109

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

2 x 2 x 297 x 95 x 161 x 109 = 1980580140

Therefore, the lowest common multiple of 297,380,644,436 is 1980580140.

LCM Formula to Find Lowest Common Multiple of 297,380,644,436

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.

297 x 380 x 644 x 436 = 31689282240

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.

297 : 1, 3, 9, 11, 27, 33, 99, 297

380 : 1, 2, 4, 5, 10, 19, 20, 38, 76, 95, 190, 380

644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644

436 : 1, 2, 4, 109, 218, 436

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 297,380,644,436, is 1.

Now, the common factors can be found like this.

297:3x 3x 3x 11

380:2x 2x 5x 19

644:2x 2x 7x 23

436:2x 2x 109

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 2 = 16

Therefore, the value for common factors is 16.

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 = 31689282240/(1x16)

LCM = 31689282240/16

LCM = 1980580140

Thus, we can understand that the LCM of 297,380,644,436 is 1980580140.
