Given numbers are 421,995,263,398

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

The LCM of 421,995,263,398 is 220338770.

Find LCM of 421,995,263,398 with Prime Factorization

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

199 x 421 x 5 x 263 x 2 = 220338770

Therefore, the lowest common multiple of 421,995,263,398 is 220338770.

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 995 x 263 x 398 = 43847415230

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

995 : 1, 5, 199, 995

263 : 1, 263

398 : 1, 2, 199, 398

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 421,995,263,398, is 1.

Now, the common factors can be found like this.

421:421

995:5x 199

263:263

398:2x 199

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

199 = 199

Therefore, the value for common factors is 199.

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 = 43847415230/(1x199)

LCM = 43847415230/199

LCM = 220338770

Thus, we can understand that the LCM of 421,995,263,398 is 220338770.
