Given numbers are 7538,2190

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

The LCM of 7538,2190 is 8254110.

Find LCM of 7538,2190 with Prime Factorization

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

2 x 3769 x 1095 = 8254110

Therefore, the lowest common multiple of 7538,2190 is 8254110.

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.

7538 x 2190 = 16508220

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.

7538 : 1, 2, 3769, 7538

2190 : 1, 2, 3, 5, 6, 10, 15, 30, 73, 146, 219, 365, 438, 730, 1095, 2190

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 7538,2190, is 2.

Now, the common factors can be found like this.

7538:2x 3769

2190:2x 3x 5x 73

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

= 1

Therefore, the value for common factors is 1.

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 = 16508220/(2x1)

LCM = 16508220/2

LCM = 8254110

Thus, we can understand that the LCM of 7538,2190 is 8254110.
