Calculate the LCM of 392,547,692,391

Given numbers are 392,547,692,391

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

The LCM of 392,547,692,391 is 14504282632.

Find LCM of 392,547,692,391 with Prime Factorization


2 392, 547, 692, 391
2 196, 547, 346, 391
98, 547, 173, 391

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

2 x 2 x 98 x 547 x 173 x 391 = 14504282632

Therefore, the lowest common multiple of 392,547,692,391 is 14504282632.

LCM Formula to Find Lowest Common Multiple of 392,547,692,391

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.

392 x 547 x 692 x 391 = 58017130528

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.

392 : 1, 2, 4, 7, 8, 14, 28, 49, 56, 98, 196, 392

547 : 1, 547

692 : 1, 2, 4, 173, 346, 692

391 : 1, 17, 23, 391

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 392,547,692,391, is 1.

Now, the common factors can be found like this.

392:2x 2x 2x 7x 7

547:547

692:2x 2x 173

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.

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 58017130528/(1x4)

LCM = 58017130528/4

LCM = 14504282632

Thus, we can understand that the LCM of 392,547,692,391 is 14504282632.
