Given numbers are 97,31,90,826

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

The LCM of 97,31,90,826 is 111770190.

Find LCM of 97,31,90,826 with Prime Factorization

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

2 x 97 x 31 x 45 x 413 = 111770190

Therefore, the lowest common multiple of 97,31,90,826 is 111770190.

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.

97 x 31 x 90 x 826 = 223540380

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.

97 : 1, 97

31 : 1, 31

90 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 30, 45, 90

826 : 1, 2, 7, 14, 59, 118, 413, 826

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 97,31,90,826, is 1.

Now, the common factors can be found like this.

97:97

31:31

90:2x 3x 3x 5

826:2x 7x 59

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 = 223540380/(1x2)

LCM = 223540380/2

LCM = 111770190

Thus, we can understand that the LCM of 97,31,90,826 is 111770190.
