Calculate the LCM of 658,878,172,564

Given numbers are 658,878,172,564

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

The LCM of 658,878,172,564 is 74526396.

Find LCM of 658,878,172,564 with Prime Factorization


2 658, 878, 172, 564
2 329, 439, 86, 282
47 329, 439, 43, 141
7, 439, 43, 3

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

2 x 2 x 47 x 7 x 439 x 43 x 3 = 74526396

Therefore, the lowest common multiple of 658,878,172,564 is 74526396.

LCM Formula to Find Lowest Common Multiple of 658,878,172,564

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.

658 x 878 x 172 x 564 = 56043849792

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.

658 : 1, 2, 7, 14, 47, 94, 329, 658

878 : 1, 2, 439, 878

172 : 1, 2, 4, 43, 86, 172

564 : 1, 2, 3, 4, 6, 12, 47, 94, 141, 188, 282, 564

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 658,878,172,564, is 2.

Now, the common factors can be found like this.

658:2x 7x 47

878:2x 439

172:2x 2x 43

564:2x 2x 3x 47

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 47 = 376

Therefore, the value for common factors is 376.

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 = 56043849792/(2x376)

LCM = 56043849792/752

LCM = 74526396

Thus, we can understand that the LCM of 658,878,172,564 is 74526396.
