Given numbers are 691,851,851,961

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

The LCM of 691,851,851,961 is 565107401.

Find LCM of 691,851,851,961 with Prime Factorization

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

23 x 37 x 691 x 1 x 1 x 961 = 565107401

Therefore, the lowest common multiple of 691,851,851,961 is 565107401.

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.

691 x 851 x 851 x 961 = 480906398251

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.

691 : 1, 691

851 : 1, 23, 37, 851

851 : 1, 23, 37, 851

961 : 1, 31, 961

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 691,851,851,961, is 1.

Now, the common factors can be found like this.

691:691

851:23x 37

851:23x 37

961:31x 31

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

23x 37 = 851

Therefore, the value for common factors is 851.

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 = 480906398251/(1x851)

LCM = 480906398251/851

LCM = 565107401

Thus, we can understand that the LCM of 691,851,851,961 is 565107401.
