Given numbers are 697,529,421,842

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

The LCM of 697,529,421,842 is 310456346.

Find LCM of 697,529,421,842 with Prime Factorization

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

421 x 697 x 529 x 1 x 2 = 310456346

Therefore, the lowest common multiple of 697,529,421,842 is 310456346.

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.

697 x 529 x 421 x 842 = 130702121666

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.

697 : 1, 17, 41, 697

529 : 1, 23, 529

421 : 1, 421

842 : 1, 2, 421, 842

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 697,529,421,842, is 1.

Now, the common factors can be found like this.

697:17x 41

529:23x 23

421:421

842:2x 421

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

421 = 421

Therefore, the value for common factors is 421.

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 = 130702121666/(1x421)

LCM = 130702121666/421

LCM = 310456346

Thus, we can understand that the LCM of 697,529,421,842 is 310456346.
