Given numbers are 689,434,538,106,472

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

The LCM of 689,434,538,106,472 is 18983366584.

Find LCM of 689,434,538,106,472 with Prime Factorization

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

2 x 53 x 13 x 217 x 269 x 1 x 236 = 18983366584

Therefore, the lowest common multiple of 689,434,538,106,472 is 18983366584.

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 434 x 538 x 106 x 472 = 8048947431616

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

434 : 1, 2, 7, 14, 31, 62, 217, 434

538 : 1, 2, 269, 538

106 : 1, 2, 53, 106

472 : 1, 2, 4, 8, 59, 118, 236, 472

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 689,434,538,106,472, is 1.

Now, the common factors can be found like this.

689:13x 53

434:2x 7x 31

538:2x 269

106:2x 53

472:2x 2x 2x 59

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 53 = 424

Therefore, the value for common factors is 424.

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 = 8048947431616/(1x424)

LCM = 8048947431616/424

LCM = 18983366584

Thus, we can understand that the LCM of 689,434,538,106,472 is 18983366584.
