Given numbers are 474,398,221,822

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

The LCM of 474,398,221,822 is 2855908302.

Find LCM of 474,398,221,822 with Prime Factorization

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

2 x 3 x 79 x 199 x 221 x 137 = 2855908302

Therefore, the lowest common multiple of 474,398,221,822 is 2855908302.

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.

474 x 398 x 221 x 822 = 34270899624

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.

474 : 1, 2, 3, 6, 79, 158, 237, 474

398 : 1, 2, 199, 398

221 : 1, 13, 17, 221

822 : 1, 2, 3, 6, 137, 274, 411, 822

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 474,398,221,822, is 1.

Now, the common factors can be found like this.

474:2x 3x 79

398:2x 199

221:13x 17

822:2x 3x 137

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 3 = 12

Therefore, the value for common factors is 12.

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 = 34270899624/(1x12)

LCM = 34270899624/12

LCM = 2855908302

Thus, we can understand that the LCM of 474,398,221,822 is 2855908302.
