Given numbers are 449,690,758,620

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

The LCM of 449,690,758,620 is 7279915380.

Find LCM of 449,690,758,620 with Prime Factorization

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

2 x 5 x 449 x 69 x 379 x 62 = 7279915380

Therefore, the lowest common multiple of 449,690,758,620 is 7279915380.

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.

449 x 690 x 758 x 620 = 145598307600

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.

449 : 1, 449

690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690

758 : 1, 2, 379, 758

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 449,690,758,620, is 1.

Now, the common factors can be found like this.

449:449

690:2x 3x 5x 23

758:2x 379

620:2x 2x 5x 31

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 5 = 20

Therefore, the value for common factors is 20.

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 = 145598307600/(1x20)

LCM = 145598307600/20

LCM = 7279915380

Thus, we can understand that the LCM of 449,690,758,620 is 7279915380.
