Given numbers are 620,734,572,340,240

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

The LCM of 620,734,572,340,240 is 6637796880.

Find LCM of 620,734,572,340,240 with Prime Factorization

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

2 x 2 x 5 x 31 x 367 x 143 x 17 x 12 = 6637796880

Therefore, the lowest common multiple of 620,734,572,340,240 is 6637796880.

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.

620 x 734 x 572 x 340 x 240 = 21240950016000

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.

620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620

734 : 1, 2, 367, 734

572 : 1, 2, 4, 11, 13, 22, 26, 44, 52, 143, 286, 572

340 : 1, 2, 4, 5, 10, 17, 20, 34, 68, 85, 170, 340

240 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 40, 48, 60, 80, 120, 240

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 620,734,572,340,240, is 2.

Now, the common factors can be found like this.

620:2x 2x 5x 31

734:2x 367

572:2x 2x 11x 13

340:2x 2x 5x 17

240:2x 2x 2x 2x 3x 5

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

2x 2x 2x 2x 2x 2x 5x 5 = 1600

Therefore, the value for common factors is 1600.

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 = 21240950016000/(2x1600)

LCM = 21240950016000/3200

LCM = 6637796880

Thus, we can understand that the LCM of 620,734,572,340,240 is 6637796880.
