Given numbers are 669,642,690,738,248

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

The LCM of 669,642,690,738,248 is 251110300680.

Find LCM of 669,642,690,738,248 with Prime Factorization

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

2 x 3 x 223 x 107 x 115 x 123 x 124 = 251110300680

Therefore, the lowest common multiple of 669,642,690,738,248 is 251110300680.

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.

669 x 642 x 690 x 738 x 248 = 54239824946880

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.

669 : 1, 3, 223, 669

642 : 1, 2, 3, 6, 107, 214, 321, 642

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

738 : 1, 2, 3, 6, 9, 18, 41, 82, 123, 246, 369, 738

248 : 1, 2, 4, 8, 31, 62, 124, 248

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 669,642,690,738,248, is 1.

Now, the common factors can be found like this.

669:3x 223

642:2x 3x 107

690:2x 3x 5x 23

738:2x 3x 3x 41

248:2x 2x 2x 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 2x 3x 3x 3 = 216

Therefore, the value for common factors is 216.

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 = 54239824946880/(1x216)

LCM = 54239824946880/216

LCM = 251110300680

Thus, we can understand that the LCM of 669,642,690,738,248 is 251110300680.
