Given numbers are 87,98,35,31,247

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

The LCM of 87,98,35,31,247 is 326417910.

Find LCM of 87,98,35,31,247 with Prime Factorization

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

7 x 87 x 14 x 5 x 31 x 247 = 326417910

Therefore, the lowest common multiple of 87,98,35,31,247 is 326417910.

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.

87 x 98 x 35 x 31 x 247 = 2284925370

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.

87 : 1, 3, 29, 87

98 : 1, 2, 7, 14, 49, 98

35 : 1, 5, 7, 35

31 : 1, 31

247 : 1, 13, 19, 247

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 87,98,35,31,247, is 1.

Now, the common factors can be found like this.

87:3x 29

98:2x 7x 7

35:5x 7

31:31

247:13x 19

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

7 = 7

Therefore, the value for common factors is 7.

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 = 2284925370/(1x7)

LCM = 2284925370/7

LCM = 326417910

Thus, we can understand that the LCM of 87,98,35,31,247 is 326417910.
