Find LCM of 428,923,279,156,717 with Prime Factorization


2 428, 923, 279, 156, 717
2 214, 923, 279, 78, 717
3 107, 923, 279, 39, 717
13 107, 923, 93, 13, 239
107, 71, 93, 1, 239

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

2 x 2 x 3 x 13 x 107 x 71 x 93 x 1 x 239 = 26341928964

Therefore, the lowest common multiple of 428,923,279,156,717 is 26341928964.

LCM Formula to Find Lowest Common Multiple of 428,923,279,156,717

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.

428 x 923 x 279 x 156 x 717 = 12328022755152

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.

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

923 : 1, 13, 71, 923

279 : 1, 3, 9, 31, 93, 279

156 : 1, 2, 3, 4, 6, 12, 13, 26, 39, 52, 78, 156

717 : 1, 3, 239, 717

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 428,923,279,156,717, is 1.

Now, the common factors can be found like this.

428:2x 2x 107

923:13x 71

279:3x 3x 31

156:2x 2x 3x 13

717:3x 239

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 3x 3x 13 = 468

Therefore, the value for common factors is 468.

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 = 12328022755152/(1x468)

LCM = 12328022755152/468

LCM = 26341928964

Thus, we can understand that the LCM of 428,923,279,156,717 is 26341928964.
