Given numbers are 424,274,689,842

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

The LCM of 424,274,689,842 is 317915624.

Find LCM of 424,274,689,842 with Prime Factorization

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

2 x 53 x 4 x 137 x 13 x 421 = 317915624

Therefore, the lowest common multiple of 424,274,689,842 is 317915624.

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.

424 x 274 x 689 x 842 = 67398112288

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.

424 : 1, 2, 4, 8, 53, 106, 212, 424

274 : 1, 2, 137, 274

689 : 1, 13, 53, 689

842 : 1, 2, 421, 842

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 424,274,689,842, is 1.

Now, the common factors can be found like this.

424:2x 2x 2x 53

274:2x 137

689:13x 53

842:2x 421

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 53 = 212

Therefore, the value for common factors is 212.

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 = 67398112288/(1x212)

LCM = 67398112288/212

LCM = 317915624

Thus, we can understand that the LCM of 424,274,689,842 is 317915624.
