Calculate the LCM of 316,390,550,656

Given numbers are 316,390,550,656

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

The LCM of 316,390,550,656 is 555812400.

Find LCM of 316,390,550,656 with Prime Factorization


2 316, 390, 550, 656
2 158, 195, 275, 328
5 79, 195, 275, 164
79, 39, 55, 164

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

2 x 2 x 5 x 79 x 39 x 55 x 164 = 555812400

Therefore, the lowest common multiple of 316,390,550,656 is 555812400.

LCM Formula to Find Lowest Common Multiple of 316,390,550,656

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.

316 x 390 x 550 x 656 = 44464992000

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.

316 : 1, 2, 4, 79, 158, 316

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

550 : 1, 2, 5, 10, 11, 22, 25, 50, 55, 110, 275, 550

656 : 1, 2, 4, 8, 16, 41, 82, 164, 328, 656

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 316,390,550,656, is 2.

Now, the common factors can be found like this.

316:2x 2x 79

390:2x 3x 5x 13

550:2x 5x 5x 11

656:2x 2x 2x 2x 41

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 5 = 40

Therefore, the value for common factors is 40.

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 = 44464992000/(2x40)

LCM = 44464992000/80

LCM = 555812400

Thus, we can understand that the LCM of 316,390,550,656 is 555812400.
