Given numbers are 478,289,938,402

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

The LCM of 478,289,938,402 is 194365794.

Find LCM of 478,289,938,402 with Prime Factorization

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

2 x 67 x 239 x 289 x 7 x 3 = 194365794

Therefore, the lowest common multiple of 478,289,938,402 is 194365794.

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 289 x 938 x 402 = 52090032792

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

289 : 1, 17, 289

938 : 1, 2, 7, 14, 67, 134, 469, 938

402 : 1, 2, 3, 6, 67, 134, 201, 402

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 478,289,938,402, is 1.

Now, the common factors can be found like this.

478:2x 239

289:17x 17

938:2x 7x 67

402:2x 3x 67

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 67 = 268

Therefore, the value for common factors is 268.

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 = 52090032792/(1x268)

LCM = 52090032792/268

LCM = 194365794

Thus, we can understand that the LCM of 478,289,938,402 is 194365794.
