Calculate the LCM of 417,909,478,948

Given numbers are 417,909,478,948

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

The LCM of 417,909,478,948 is 9542532924.

Find LCM of 417,909,478,948 with Prime Factorization


2 417, 909, 478, 948
3 417, 909, 239, 474
139, 303, 239, 158

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

2 x 3 x 139 x 303 x 239 x 158 = 9542532924

Therefore, the lowest common multiple of 417,909,478,948 is 9542532924.

LCM Formula to Find Lowest Common Multiple of 417,909,478,948

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.

417 x 909 x 478 x 948 = 171765592632

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.

417 : 1, 3, 139, 417

909 : 1, 3, 9, 101, 303, 909

478 : 1, 2, 239, 478

948 : 1, 2, 3, 4, 6, 12, 79, 158, 237, 316, 474, 948

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 417,909,478,948, is 1.

Now, the common factors can be found like this.

417:3x 139

909:3x 3x 101

478:2x 239

948:2x 2x 3x 79

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

2x 3x 3 = 18

Therefore, the value for common factors is 18.

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 = 171765592632/(1x18)

LCM = 171765592632/18

LCM = 9542532924

Thus, we can understand that the LCM of 417,909,478,948 is 9542532924.
