Calculate the LCM of 421,170,499,391

Given numbers are 421,170,499,391

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

The LCM of 421,170,499,391 is 821408890.

Find LCM of 421,170,499,391 with Prime Factorization

17	421, 170, 499, 391
	421, 10, 499, 23

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

17 x 421 x 10 x 499 x 23 = 821408890

Therefore, the lowest common multiple of 421,170,499,391 is 821408890.

LCM Formula to Find Lowest Common Multiple of 421,170,499,391

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 170 x 499 x 391 = 13963951130

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

170 : 1, 2, 5, 10, 17, 34, 85, 170

499 : 1, 499

391 : 1, 17, 23, 391

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 421,170,499,391, is 1.

Now, the common factors can be found like this.

421:421

170:2x 5x 17

499:499

391:17x 23

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 = 13963951130/(1x17)

LCM = 13963951130/17

LCM = 821408890

Thus, we can understand that the LCM of 421,170,499,391 is 821408890.
