Calculate the LCM of 391,403,527,388

Given numbers are 391,403,527,388

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

The LCM of 391,403,527,388 is 61138324.

Find LCM of 391,403,527,388 with Prime Factorization


17 391, 403, 527, 388
31 23, 403, 31, 388
23, 13, 1, 388

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

17 x 31 x 23 x 13 x 1 x 388 = 61138324

Therefore, the lowest common multiple of 391,403,527,388 is 61138324.

LCM Formula to Find Lowest Common Multiple of 391,403,527,388

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.

391 x 403 x 527 x 388 = 32219896748

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.

391 : 1, 17, 23, 391

403 : 1, 13, 31, 403

527 : 1, 17, 31, 527

388 : 1, 2, 4, 97, 194, 388

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 391,403,527,388, is 1.

Now, the common factors can be found like this.

391:17x 23

403:13x 31

527:17x 31

388:2x 2x 97

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

17x 31 = 527

Therefore, the value for common factors is 527.

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 = 32219896748/(1x527)

LCM = 32219896748/527

LCM = 61138324

Thus, we can understand that the LCM of 391,403,527,388 is 61138324.
