Given numbers are 452,421,398,434

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

The LCM of 452,421,398,434 is 8217379436.

Find LCM of 452,421,398,434 with Prime Factorization

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

2 x 226 x 421 x 199 x 217 = 8217379436

Therefore, the lowest common multiple of 452,421,398,434 is 8217379436.

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.

452 x 421 x 398 x 434 = 32869517744

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.

452 : 1, 2, 4, 113, 226, 452

421 : 1, 421

398 : 1, 2, 199, 398

434 : 1, 2, 7, 14, 31, 62, 217, 434

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 452,421,398,434, is 1.

Now, the common factors can be found like this.

452:2x 2x 113

421:421

398:2x 199

434:2x 7x 31

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 = 32869517744/(1x4)

LCM = 32869517744/4

LCM = 8217379436

Thus, we can understand that the LCM of 452,421,398,434 is 8217379436.
