Given numbers are 689,329,278,974

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

The LCM of 689,329,278,974 is 30689433866.

Find LCM of 689,329,278,974 with Prime Factorization

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

2 x 689 x 329 x 139 x 487 = 30689433866

Therefore, the lowest common multiple of 689,329,278,974 is 30689433866.

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.

689 x 329 x 278 x 974 = 61378867732

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.

689 : 1, 13, 53, 689

329 : 1, 7, 47, 329

278 : 1, 2, 139, 278

974 : 1, 2, 487, 974

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 689,329,278,974, is 1.

Now, the common factors can be found like this.

689:13x 53

329:7x 47

278:2x 139

974:2x 487

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

2 = 2

Therefore, the value for common factors is 2.

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 = 61378867732/(1x2)

LCM = 61378867732/2

LCM = 30689433866

Thus, we can understand that the LCM of 689,329,278,974 is 30689433866.
