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

2 x 2 x 2 x 2 x 5 x 7 x 249 x 1 x 19 x 11 = 29142960

Therefore, the lowest common multiple of 249,560,665,880 is 29142960.

LCM Formula to Find Lowest Common Multiple of 249,560,665,880

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.

249 x 560 x 665 x 880 = 81600288000

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.

249 : 1, 3, 83, 249

560 : 1, 2, 4, 5, 7, 8, 10, 14, 16, 20, 28, 35, 40, 56, 70, 80, 112, 140, 280, 560

665 : 1, 5, 7, 19, 35, 95, 133, 665

880 : 1, 2, 4, 5, 8, 10, 11, 16, 20, 22, 40, 44, 55, 80, 88, 110, 176, 220, 440, 880

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 249,560,665,880, is 1.

Now, the common factors can be found like this.

249:3x 83

560:2x 2x 2x 2x 5x 7

665:5x 7x 19

880:2x 2x 2x 2x 5x 11

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 5x 5x 7 = 2800

Therefore, the value for common factors is 2800.

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 = 81600288000/(1x2800)

LCM = 81600288000/2800

LCM = 29142960

Thus, we can understand that the LCM of 249,560,665,880 is 29142960.
