Given numbers are 438,473,428,938

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

The LCM of 438,473,428,938 is 20793225684.

Find LCM of 438,473,428,938 with Prime Factorization

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

2 x 219 x 473 x 214 x 469 = 20793225684

Therefore, the lowest common multiple of 438,473,428,938 is 20793225684.

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.

438 x 473 x 428 x 938 = 83172902736

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.

438 : 1, 2, 3, 6, 73, 146, 219, 438

473 : 1, 11, 43, 473

428 : 1, 2, 4, 107, 214, 428

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 438,473,428,938, is 1.

Now, the common factors can be found like this.

438:2x 3x 73

473:11x 43

428:2x 2x 107

938:2x 7x 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 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 = 83172902736/(1x4)

LCM = 83172902736/4

LCM = 20793225684

Thus, we can understand that the LCM of 438,473,428,938 is 20793225684.
