Given numbers are 76,88,31,947

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

The LCM of 76,88,31,947 is 49084904.

Find LCM of 76,88,31,947 with Prime Factorization

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

2 x 2 x 19 x 22 x 31 x 947 = 49084904

Therefore, the lowest common multiple of 76,88,31,947 is 49084904.

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.

76 x 88 x 31 x 947 = 196339616

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.

76 : 1, 2, 4, 19, 38, 76

88 : 1, 2, 4, 8, 11, 22, 44, 88

31 : 1, 31

947 : 1, 947

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 76,88,31,947, is 1.

Now, the common factors can be found like this.

76:2x 2x 19

88:2x 2x 2x 11

31:31

947:947

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 196339616/(1x4)

LCM = 196339616/4

LCM = 49084904

Thus, we can understand that the LCM of 76,88,31,947 is 49084904.

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

• LCM of 23, 85, 17, 841
