The LCM of 578,175,391,574 is 95384450.

Find LCM of 578,175,391,574 with Prime Factorization


2 578, 175, 391, 574
7 289, 175, 391, 287
17 289, 25, 391, 41
17, 25, 23, 41

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

2 x 7 x 17 x 17 x 25 x 23 x 41 = 95384450

Therefore, the lowest common multiple of 578,175,391,574 is 95384450.

LCM Formula to Find Lowest Common Multiple of 578,175,391,574

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.

578 x 175 x 391 x 574 = 22701499100

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.

578 : 1, 2, 17, 34, 289, 578

175 : 1, 5, 7, 25, 35, 175

391 : 1, 17, 23, 391

574 : 1, 2, 7, 14, 41, 82, 287, 574

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 578,175,391,574, is 1.

Now, the common factors can be found like this.

578:2x 17x 17

175:5x 5x 7

391:17x 23

574:2x 7x 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 7x 17 = 238

Therefore, the value for common factors is 238.

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 = 22701499100/(1x238)

LCM = 22701499100/238

LCM = 95384450

Thus, we can understand that the LCM of 578,175,391,574 is 95384450.
