Calculate the LCM of 843,638,368,434

Given numbers are 843,638,368,434

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

The LCM of 843,638,368,434 is 21474635952.

Find LCM of 843,638,368,434 with Prime Factorization


2 843, 638, 368, 434
843, 319, 184, 217

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

2 x 843 x 319 x 184 x 217 = 21474635952

Therefore, the lowest common multiple of 843,638,368,434 is 21474635952.

LCM Formula to Find Lowest Common Multiple of 843,638,368,434

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.

843 x 638 x 368 x 434 = 85898543808

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.

843 : 1, 3, 281, 843

638 : 1, 2, 11, 22, 29, 58, 319, 638

368 : 1, 2, 4, 8, 16, 23, 46, 92, 184, 368

434 : 1, 2, 7, 14, 31, 62, 217, 434

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 843,638,368,434, is 1.

Now, the common factors can be found like this.

843:3x 281

638:2x 11x 29

368:2x 2x 2x 2x 23

434:2x 7x 31

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 85898543808/(1x4)

LCM = 85898543808/4

LCM = 21474635952

Thus, we can understand that the LCM of 843,638,368,434 is 21474635952.
