Given numbers are 790,821,560,990,247

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

The LCM of 790,821,560,990,247 is 888158391120.

Find LCM of 790,821,560,990,247 with Prime Factorization

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

2 x 5 x 79 x 821 x 56 x 99 x 247 = 888158391120

Therefore, the lowest common multiple of 790,821,560,990,247 is 888158391120.

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.

790 x 821 x 560 x 990 x 247 = 88815839112000

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.

790 : 1, 2, 5, 10, 79, 158, 395, 790

821 : 1, 821

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

990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990

247 : 1, 13, 19, 247

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 790,821,560,990,247, is 1.

Now, the common factors can be found like this.

790:2x 5x 79

821:821

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

990:2x 3x 3x 5x 11

247:13x 19

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 5x 5 = 100

Therefore, the value for common factors is 100.

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 = 88815839112000/(1x100)

LCM = 88815839112000/100

LCM = 888158391120

Thus, we can understand that the LCM of 790,821,560,990,247 is 888158391120.
