Given numbers are 1574,2440

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

The LCM of 1574,2440 is 1920280.

Find LCM of 1574,2440 with Prime Factorization

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

2 x 787 x 1220 = 1920280

Therefore, the lowest common multiple of 1574,2440 is 1920280.

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.

1574 x 2440 = 3840560

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.

1574 : 1, 2, 787, 1574

2440 : 1, 2, 4, 5, 8, 10, 20, 40, 61, 122, 244, 305, 488, 610, 1220, 2440

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 1574,2440, is 2.

Now, the common factors can be found like this.

1574:2x 787

2440:2x 2x 2x 5x 61

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 = 3840560/(2x1)

LCM = 3840560/2

LCM = 1920280

Thus, we can understand that the LCM of 1574,2440 is 1920280.
