Given numbers are 542,436,821

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

The LCM of 542,436,821 is 97006076.

Find LCM of 542,436,821 with Prime Factorization

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

2 x 271 x 218 x 821 = 97006076

Therefore, the lowest common multiple of 542,436,821 is 97006076.

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.

542 x 436 x 821 = 194012152

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.

542 : 1, 2, 271, 542

436 : 1, 2, 4, 109, 218, 436

821 : 1, 821

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 542,436,821, is 1.

Now, the common factors can be found like this.

542:2x 271

436:2x 2x 109

821:821

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

2 = 2

Therefore, the value for common factors is 2.

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 = 194012152/(1x2)

LCM = 194012152/2

LCM = 97006076

Thus, we can understand that the LCM of 542,436,821 is 97006076.

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

• LCM of 802, 391, 529
• LCM of 594, 479, 277
