Given numbers are 1390,2655

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

The LCM of 1390,2655 is 738090.

Find LCM of 1390,2655 with Prime Factorization

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

5 x 278 x 531 = 738090

Therefore, the lowest common multiple of 1390,2655 is 738090.

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.

1390 x 2655 = 3690450

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.

1390 : 1, 2, 5, 10, 139, 278, 695, 1390

2655 : 1, 3, 5, 9, 15, 45, 59, 177, 295, 531, 885, 2655

5 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 1390,2655, is 5.

Now, the common factors can be found like this.

1390:2x 5x 139

2655:3x 3x 5x 59

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 = 3690450/(5x1)

LCM = 3690450/5

LCM = 738090

Thus, we can understand that the LCM of 1390,2655 is 738090.
