Calculate the LCM of 478,266,868,628

Given numbers are 478,266,868,628

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

The LCM of 478,266,868,628 is 618829316.

Find LCM of 478,266,868,628 with Prime Factorization


2 478, 266, 868, 628
2 239, 133, 434, 314
7 239, 133, 217, 157
239, 19, 31, 157

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

2 x 2 x 7 x 239 x 19 x 31 x 157 = 618829316

Therefore, the lowest common multiple of 478,266,868,628 is 618829316.

LCM Formula to Find Lowest Common Multiple of 478,266,868,628

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.

478 x 266 x 868 x 628 = 69308883392

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.

478 : 1, 2, 239, 478

266 : 1, 2, 7, 14, 19, 38, 133, 266

868 : 1, 2, 4, 7, 14, 28, 31, 62, 124, 217, 434, 868

628 : 1, 2, 4, 157, 314, 628

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 478,266,868,628, is 2.

Now, the common factors can be found like this.

478:2x 239

266:2x 7x 19

868:2x 2x 7x 31

628:2x 2x 157

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 7 = 56

Therefore, the value for common factors is 56.

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 = 69308883392/(2x56)

LCM = 69308883392/112

LCM = 618829316

Thus, we can understand that the LCM of 478,266,868,628 is 618829316.
