Given numbers are 697,638,766,822

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

The LCM of 697,638,766,822 is 69999357318.

Find LCM of 697,638,766,822 with Prime Factorization

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

2 x 697 x 319 x 383 x 411 = 69999357318

Therefore, the lowest common multiple of 697,638,766,822 is 69999357318.

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 638 x 766 x 822 = 279997429272

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

638 : 1, 2, 11, 22, 29, 58, 319, 638

766 : 1, 2, 383, 766

822 : 1, 2, 3, 6, 137, 274, 411, 822

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 697,638,766,822, is 1.

Now, the common factors can be found like this.

697:17x 41

638:2x 11x 29

766:2x 383

822:2x 3x 137

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 279997429272/(1x4)

LCM = 279997429272/4

LCM = 69999357318

Thus, we can understand that the LCM of 697,638,766,822 is 69999357318.
