Calculate the LCM of 344,286,249,769,640

Given numbers are 344,286,249,769,640

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

The LCM of 344,286,249,769,640 is 753546668160.

Find LCM of 344,286,249,769,640 with Prime Factorization


2 344, 286, 249, 769, 640
2 172, 143, 249, 769, 320
2 86, 143, 249, 769, 160
43, 143, 249, 769, 80

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

2 x 2 x 2 x 43 x 143 x 249 x 769 x 80 = 753546668160

Therefore, the lowest common multiple of 344,286,249,769,640 is 753546668160.

LCM Formula to Find Lowest Common Multiple of 344,286,249,769,640

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.

344 x 286 x 249 x 769 x 640 = 12056746690560

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.

344 : 1, 2, 4, 8, 43, 86, 172, 344

286 : 1, 2, 11, 13, 22, 26, 143, 286

249 : 1, 3, 83, 249

769 : 1, 769

640 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 344,286,249,769,640, is 1.

Now, the common factors can be found like this.

344:2x 2x 2x 43

286:2x 11x 13

249:3x 83

769:769

640:2x 2x 2x 2x 2x 2x 2x 5

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 = 12056746690560/(1x16)

LCM = 12056746690560/16

LCM = 753546668160

Thus, we can understand that the LCM of 344,286,249,769,640 is 753546668160.
