Given numbers are 842,905,142

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

The LCM of 842,905,142 is 54102710.

Find LCM of 842,905,142 with Prime Factorization

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

2 x 421 x 905 x 71 = 54102710

Therefore, the lowest common multiple of 842,905,142 is 54102710.

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.

842 x 905 x 142 = 108205420

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.

842 : 1, 2, 421, 842

905 : 1, 5, 181, 905

142 : 1, 2, 71, 142

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 842,905,142, is 1.

Now, the common factors can be found like this.

842:2x 421

905:5x 181

142:2x 71

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 = 108205420/(1x2)

LCM = 108205420/2

LCM = 54102710

Thus, we can understand that the LCM of 842,905,142 is 54102710.

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

• LCM of 665, 804, 693
• LCM of 923, 486, 387
