The LCM of 788,288,819,428 is 552438432.

Find LCM of 788,288,819,428 with Prime Factorization


2 788, 288, 819, 428
2 394, 144, 819, 214
3 197, 72, 819, 107
3 197, 24, 273, 107
197, 8, 91, 107

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

2 x 2 x 3 x 3 x 197 x 8 x 91 x 107 = 552438432

Therefore, the lowest common multiple of 788,288,819,428 is 552438432.

LCM Formula to Find Lowest Common Multiple of 788,288,819,428

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.

788 x 288 x 819 x 428 = 79551134208

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.

788 : 1, 2, 4, 197, 394, 788

288 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 32, 36, 48, 72, 96, 144, 288

819 : 1, 3, 7, 9, 13, 21, 39, 63, 91, 117, 273, 819

428 : 1, 2, 4, 107, 214, 428

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 788,288,819,428, is 1.

Now, the common factors can be found like this.

788:2x 2x 197

288:2x 2x 2x 2x 2x 3x 3

819:3x 3x 7x 13

428:2x 2x 107

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 3x 3 = 144

Therefore, the value for common factors is 144.

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 = 79551134208/(1x144)

LCM = 79551134208/144

LCM = 552438432

Thus, we can understand that the LCM of 788,288,819,428 is 552438432.
