Given numbers are 842,690,281,562

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

The LCM of 842,690,281,562 is 81627690.

Find LCM of 842,690,281,562 with Prime Factorization

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

2 x 281 x 421 x 345 x 1 x 1 = 81627690

Therefore, the lowest common multiple of 842,690,281,562 is 81627690.

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.

842 x 690 x 281 x 562 = 91749523560

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.

842 : 1, 2, 421, 842

690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690

281 : 1, 281

562 : 1, 2, 281, 562

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 842,690,281,562, is 1.

Now, the common factors can be found like this.

842:2x 421

690:2x 3x 5x 23

281:281

562:2x 281

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 281 = 1124

Therefore, the value for common factors is 1124.

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 = 91749523560/(1x1124)

LCM = 91749523560/1124

LCM = 81627690

Thus, we can understand that the LCM of 842,690,281,562 is 81627690.
