Given numbers are 697,211,787,211

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

The LCM of 697,211,787,211 is 115741729.

Find LCM of 697,211,787,211 with Prime Factorization

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

211 x 697 x 1 x 787 x 1 = 115741729

Therefore, the lowest common multiple of 697,211,787,211 is 115741729.

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 211 x 787 x 211 = 24421504819

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

211 : 1, 211

787 : 1, 787

211 : 1, 211

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 697,211,787,211, is 1.

Now, the common factors can be found like this.

697:17x 41

211:211

787:787

211:211

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

211 = 211

Therefore, the value for common factors is 211.

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 = 24421504819/(1x211)

LCM = 24421504819/211

LCM = 115741729

Thus, we can understand that the LCM of 697,211,787,211 is 115741729.
