Given numbers are 669,392,794,438

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

The LCM of 669,392,794,438 is 7600209288.

Find LCM of 669,392,794,438 with Prime Factorization

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

2 x 3 x 223 x 196 x 397 x 73 = 7600209288

Therefore, the lowest common multiple of 669,392,794,438 is 7600209288.

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 392 x 794 x 438 = 91202511456

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

392 : 1, 2, 4, 7, 8, 14, 28, 49, 56, 98, 196, 392

794 : 1, 2, 397, 794

438 : 1, 2, 3, 6, 73, 146, 219, 438

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 669,392,794,438, is 1.

Now, the common factors can be found like this.

669:3x 223

392:2x 2x 2x 7x 7

794:2x 397

438:2x 3x 73

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 3 = 12

Therefore, the value for common factors is 12.

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 = 91202511456/(1x12)

LCM = 91202511456/12

LCM = 7600209288

Thus, we can understand that the LCM of 669,392,794,438 is 7600209288.
