Find LCM of 355,168,994,432 with Prime Factorization


2 355, 168, 994, 432
2 355, 84, 497, 216
2 355, 42, 497, 108
3 355, 21, 497, 54
7 355, 7, 497, 18
71 355, 1, 71, 18
5, 1, 1, 18

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

2 x 2 x 2 x 3 x 7 x 71 x 5 x 1 x 1 x 18 = 1073520

Therefore, the lowest common multiple of 355,168,994,432 is 1073520.

LCM Formula to Find Lowest Common Multiple of 355,168,994,432

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.

355 x 168 x 994 x 432 = 25609893120

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.

355 : 1, 5, 71, 355

168 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 21, 24, 28, 42, 56, 84, 168

994 : 1, 2, 7, 14, 71, 142, 497, 994

432 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 27, 36, 48, 54, 72, 108, 144, 216, 432

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 355,168,994,432, is 1.

Now, the common factors can be found like this.

355:5x 71

168:2x 2x 2x 3x 7

994:2x 7x 71

432:2x 2x 2x 2x 3x 3x 3

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 7x 71 = 23856

Therefore, the value for common factors is 23856.

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 = 25609893120/(1x23856)

LCM = 25609893120/23856

LCM = 1073520

Thus, we can understand that the LCM of 355,168,994,432 is 1073520.
