Calculate the LCM of 419,289,620,512

Given numbers are 419,289,620,512

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

The LCM of 419,289,620,512 is 9609781760.

Find LCM of 419,289,620,512 with Prime Factorization


2 419, 289, 620, 512
2 419, 289, 310, 256
419, 289, 155, 128

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

2 x 2 x 419 x 289 x 155 x 128 = 9609781760

Therefore, the lowest common multiple of 419,289,620,512 is 9609781760.

LCM Formula to Find Lowest Common Multiple of 419,289,620,512

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.

419 x 289 x 620 x 512 = 38439127040

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.

419 : 1, 419

289 : 1, 17, 289

620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620

512 : 1, 2, 4, 8, 16, 32, 64, 128, 256, 512

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 419,289,620,512, is 1.

Now, the common factors can be found like this.

419:419

289:17x 17

620:2x 2x 5x 31

512:2x 2x 2x 2x 2x 2x 2x 2x 2

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 = 38439127040/(1x4)

LCM = 38439127040/4

LCM = 9609781760

Thus, we can understand that the LCM of 419,289,620,512 is 9609781760.
