Given numbers are 697,644,713,261

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

The LCM of 697,644,713,261 is 3631790988.

Find LCM of 697,644,713,261 with Prime Factorization

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

23 x 697 x 28 x 31 x 261 = 3631790988

Therefore, the lowest common multiple of 697,644,713,261 is 3631790988.

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 644 x 713 x 261 = 83531192724

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

644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644

713 : 1, 23, 31, 713

261 : 1, 3, 9, 29, 87, 261

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 697,644,713,261, is 1.

Now, the common factors can be found like this.

697:17x 41

644:2x 2x 7x 23

713:23x 31

261:3x 3x 29

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

23 = 23

Therefore, the value for common factors is 23.

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 = 83531192724/(1x23)

LCM = 83531192724/23

LCM = 3631790988

Thus, we can understand that the LCM of 697,644,713,261 is 3631790988.
