Given numbers are 421,549,542,426

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

The LCM of 421,549,542,426 is 8894306178.

Find LCM of 421,549,542,426 with Prime Factorization

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

2 x 3 x 421 x 183 x 271 x 71 = 8894306178

Therefore, the lowest common multiple of 421,549,542,426 is 8894306178.

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.

421 x 549 x 542 x 426 = 53365837068

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.

421 : 1, 421

549 : 1, 3, 9, 61, 183, 549

542 : 1, 2, 271, 542

426 : 1, 2, 3, 6, 71, 142, 213, 426

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 421,549,542,426, is 1.

Now, the common factors can be found like this.

421:421

549:3x 3x 61

542:2x 271

426:2x 3x 71

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

2x 3 = 6

Therefore, the value for common factors is 6.

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 = 53365837068/(1x6)

LCM = 53365837068/6

LCM = 8894306178

Thus, we can understand that the LCM of 421,549,542,426 is 8894306178.
