Given numbers are 302,49,642

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

The LCM of 302,49,642 is 4750158.

Find LCM of 302,49,642 with Prime Factorization

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

2 x 151 x 49 x 321 = 4750158

Therefore, the lowest common multiple of 302,49,642 is 4750158.

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.

302 x 49 x 642 = 9500316

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.

302 : 1, 2, 151, 302

49 : 1, 7, 49

642 : 1, 2, 3, 6, 107, 214, 321, 642

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 302,49,642, is 1.

Now, the common factors can be found like this.

302:2x 151

49:7x 7

642:2x 3x 107

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 = 9500316/(1x2)

LCM = 9500316/2

LCM = 4750158

Thus, we can understand that the LCM of 302,49,642 is 4750158.

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

• LCM of 331, 49, 184
• LCM of 304, 27, 337
