Calculate the LCM of 187,42,456

Given numbers are 187,42,456

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

The LCM of 187,42,456 is 596904.

Find LCM of 187,42,456 with Prime Factorization


2 187, 42, 456
3 187, 21, 228
187, 7, 76

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

2 x 3 x 187 x 7 x 76 = 596904

Therefore, the lowest common multiple of 187,42,456 is 596904.

LCM Formula to Find Lowest Common Multiple of 187,42,456

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.

187 x 42 x 456 = 3581424

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.

187 : 1, 11, 17, 187

42 : 1, 2, 3, 6, 7, 14, 21, 42

456 : 1, 2, 3, 4, 6, 8, 12, 19, 24, 38, 57, 76, 114, 152, 228, 456

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 187,42,456, is 1.

Now, the common factors can be found like this.

187:11x 17

42:2x 3x 7

456:2x 2x 2x 3x 19

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

2x 3 = 6

Therefore, the value for common factors is 6.

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 = 3581424/(1x6)

LCM = 3581424/6

LCM = 596904

Thus, we can understand that the LCM of 187,42,456 is 596904.
