Calculate the LCM of 425,431,475,391

Given numbers are 425,431,475,391

The least common multiple of numbers can be find using the prime factorization method or LCM formula.

The LCM of 425,431,475,391 is 80047475.

Find LCM of 425,431,475,391 with Prime Factorization


5 425, 431, 475, 391
5 85, 431, 95, 391
17 17, 431, 19, 391
1, 431, 19, 23

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

5 x 5 x 17 x 1 x 431 x 19 x 23 = 80047475

Therefore, the lowest common multiple of 425,431,475,391 is 80047475.

LCM Formula to Find Lowest Common Multiple of 425,431,475,391

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.

425 x 431 x 475 x 391 = 34020176875

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.

425 : 1, 5, 17, 25, 85, 425

431 : 1, 431

475 : 1, 5, 19, 25, 95, 475

391 : 1, 17, 23, 391

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 425,431,475,391, is 1.

Now, the common factors can be found like this.

425:5x 5x 17

431:431

475:5x 5x 19

391:17x 23

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

5x 5x 17 = 425

Therefore, the value for common factors is 425.

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 = 34020176875/(1x425)

LCM = 34020176875/425

LCM = 80047475

Thus, we can understand that the LCM of 425,431,475,391 is 80047475.
