Given numbers are 421,799,442

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

The LCM of 421,799,442 is 8745854.

Find LCM of 421,799,442 with Prime Factorization

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

17 x 421 x 47 x 26 = 8745854

Therefore, the lowest common multiple of 421,799,442 is 8745854.

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 799 x 442 = 148679518

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

799 : 1, 17, 47, 799

442 : 1, 2, 13, 17, 26, 34, 221, 442

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 421,799,442, is 1.

Now, the common factors can be found like this.

421:421

799:17x 47

442:2x 13x 17

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

17 = 17

Therefore, the value for common factors is 17.

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 = 148679518/(1x17)

LCM = 148679518/17

LCM = 8745854

Thus, we can understand that the LCM of 421,799,442 is 8745854.

Here are some samples of LCM of two or more Numbers calculations.

• LCM of 814, 550, 696
• LCM of 590, 922, 585
