Given numbers are 424,756,128,340

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

The LCM of 424,756,128,340 is 108984960.

Find LCM of 424,756,128,340 with Prime Factorization

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

2 x 2 x 2 x 53 x 189 x 16 x 85 = 108984960

Therefore, the lowest common multiple of 424,756,128,340 is 108984960.

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.

424 x 756 x 128 x 340 = 13950074880

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.

424 : 1, 2, 4, 8, 53, 106, 212, 424

756 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 27, 28, 36, 42, 54, 63, 84, 108, 126, 189, 252, 378, 756

128 : 1, 2, 4, 8, 16, 32, 64, 128

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

4 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 424,756,128,340, is 4.

Now, the common factors can be found like this.

424:2x 2x 2x 53

756:2x 2x 3x 3x 3x 7

128:2x 2x 2x 2x 2x 2x 2

340:2x 2x 5x 17

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 2 = 32

Therefore, the value for common factors is 32.

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 = 13950074880/(4x32)

LCM = 13950074880/128

LCM = 108984960

Thus, we can understand that the LCM of 424,756,128,340 is 108984960.
