Calculate the LCM of 495,358,390,289

Given numbers are 495,358,390,289

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

The LCM of 495,358,390,289 is 665777970.

Find LCM of 495,358,390,289 with Prime Factorization


2 495, 358, 390, 289
3 495, 179, 195, 289
5 165, 179, 65, 289
33, 179, 13, 289

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

2 x 3 x 5 x 33 x 179 x 13 x 289 = 665777970

Therefore, the lowest common multiple of 495,358,390,289 is 665777970.

LCM Formula to Find Lowest Common Multiple of 495,358,390,289

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.

495 x 358 x 390 x 289 = 19973339100

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.

495 : 1, 3, 5, 9, 11, 15, 33, 45, 55, 99, 165, 495

358 : 1, 2, 179, 358

390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390

289 : 1, 17, 289

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 495,358,390,289, is 1.

Now, the common factors can be found like this.

495:3x 3x 5x 11

358:2x 179

390:2x 3x 5x 13

289:17x 17

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

2x 3x 5 = 30

Therefore, the value for common factors is 30.

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 = 19973339100/(1x30)

LCM = 19973339100/30

LCM = 665777970

Thus, we can understand that the LCM of 495,358,390,289 is 665777970.
