Given numbers are 694,618,721,904

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

The LCM of 694,618,721,904 is 678507144.

Find LCM of 694,618,721,904 with Prime Factorization

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

2 x 103 x 347 x 3 x 7 x 452 = 678507144

Therefore, the lowest common multiple of 694,618,721,904 is 678507144.

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.

694 x 618 x 721 x 904 = 279544943328

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.

694 : 1, 2, 347, 694

618 : 1, 2, 3, 6, 103, 206, 309, 618

721 : 1, 7, 103, 721

904 : 1, 2, 4, 8, 113, 226, 452, 904

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 694,618,721,904, is 1.

Now, the common factors can be found like this.

694:2x 347

618:2x 3x 103

721:7x 103

904:2x 2x 2x 113

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 103 = 412

Therefore, the value for common factors is 412.

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 = 279544943328/(1x412)

LCM = 279544943328/412

LCM = 678507144

Thus, we can understand that the LCM of 694,618,721,904 is 678507144.
