Given numbers are 329,140,639,778

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

The LCM of 329,140,639,778 is 1635597180.

Find LCM of 329,140,639,778 with Prime Factorization

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

2 x 7 x 47 x 10 x 639 x 389 = 1635597180

Therefore, the lowest common multiple of 329,140,639,778 is 1635597180.

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.

329 x 140 x 639 x 778 = 22898360520

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.

329 : 1, 7, 47, 329

140 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 70, 140

639 : 1, 3, 9, 71, 213, 639

778 : 1, 2, 389, 778

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 329,140,639,778, is 1.

Now, the common factors can be found like this.

329:7x 47

140:2x 2x 5x 7

639:3x 3x 71

778:2x 389

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2x 7 = 14

Therefore, the value for common factors is 14.

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 = 22898360520/(1x14)

LCM = 22898360520/14

LCM = 1635597180

Thus, we can understand that the LCM of 329,140,639,778 is 1635597180.
