Given numbers are 515,74,156

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

The LCM of 515,74,156 is 2972580.

Find LCM of 515,74,156 with Prime Factorization

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

2 x 515 x 37 x 78 = 2972580

Therefore, the lowest common multiple of 515,74,156 is 2972580.

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.

515 x 74 x 156 = 5945160

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.

515 : 1, 5, 103, 515

74 : 1, 2, 37, 74

156 : 1, 2, 3, 4, 6, 12, 13, 26, 39, 52, 78, 156

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 515,74,156, is 1.

Now, the common factors can be found like this.

515:5x 103

74:2x 37

156:2x 2x 3x 13

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 = 5945160/(1x2)

LCM = 5945160/2

LCM = 2972580

Thus, we can understand that the LCM of 515,74,156 is 2972580.

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

• LCM of 887, 84, 692
• LCM of 954, 15, 143
