The LCM of 818,380,988,444 is 224271060.

Find LCM of 818,380,988,444 with Prime Factorization


2 818, 380, 988, 444
2 409, 190, 494, 222
19 409, 95, 247, 111
409, 5, 13, 111

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

2 x 2 x 19 x 409 x 5 x 13 x 111 = 224271060

Therefore, the lowest common multiple of 818,380,988,444 is 224271060.

LCM Formula to Find Lowest Common Multiple of 818,380,988,444

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.

818 x 380 x 988 x 444 = 136356804480

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.

818 : 1, 2, 409, 818

380 : 1, 2, 4, 5, 10, 19, 20, 38, 76, 95, 190, 380

988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988

444 : 1, 2, 3, 4, 6, 12, 37, 74, 111, 148, 222, 444

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 818,380,988,444, is 2.

Now, the common factors can be found like this.

818:2x 409

380:2x 2x 5x 19

988:2x 2x 13x 19

444:2x 2x 3x 37

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 2x 19 = 304

Therefore, the value for common factors is 304.

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 = 136356804480/(2x304)

LCM = 136356804480/608

LCM = 224271060

Thus, we can understand that the LCM of 818,380,988,444 is 224271060.
