Given numbers are 472,91,842

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

The LCM of 472,91,842 is 18082792.

Find LCM of 472,91,842 with Prime Factorization

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

2 x 236 x 91 x 421 = 18082792

Therefore, the lowest common multiple of 472,91,842 is 18082792.

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.

472 x 91 x 842 = 36165584

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.

472 : 1, 2, 4, 8, 59, 118, 236, 472

91 : 1, 7, 13, 91

842 : 1, 2, 421, 842

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 472,91,842, is 1.

Now, the common factors can be found like this.

472:2x 2x 2x 59

91:7x 13

842:2x 421

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 = 36165584/(1x2)

LCM = 36165584/2

LCM = 18082792

Thus, we can understand that the LCM of 472,91,842 is 18082792.

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

• LCM of 744, 73, 972
• LCM of 277, 65, 432
