Given numbers are 211,970,689,620

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

The LCM of 211,970,689,620 is 8743093060.

Find LCM of 211,970,689,620 with Prime Factorization

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

2 x 5 x 211 x 97 x 689 x 62 = 8743093060

Therefore, the lowest common multiple of 211,970,689,620 is 8743093060.

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.

211 x 970 x 689 x 620 = 87430930600

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.

211 : 1, 211

970 : 1, 2, 5, 10, 97, 194, 485, 970

689 : 1, 13, 53, 689

620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 211,970,689,620, is 1.

Now, the common factors can be found like this.

211:211

970:2x 5x 97

689:13x 53

620:2x 2x 5x 31

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

2x 5 = 10

Therefore, the value for common factors is 10.

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 = 87430930600/(1x10)

LCM = 87430930600/10

LCM = 8743093060

Thus, we can understand that the LCM of 211,970,689,620 is 8743093060.
