Given numbers are 642,691,889,127

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

The LCM of 642,691,889,127 is 394379958.

Find LCM of 642,691,889,127 with Prime Factorization

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

127 x 642 x 691 x 7 x 1 = 394379958

Therefore, the lowest common multiple of 642,691,889,127 is 394379958.

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.

642 x 691 x 889 x 127 = 50086254666

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.

642 : 1, 2, 3, 6, 107, 214, 321, 642

691 : 1, 691

889 : 1, 7, 127, 889

127 : 1, 127

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 642,691,889,127, is 1.

Now, the common factors can be found like this.

642:2x 3x 107

691:691

889:7x 127

127:127

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

127 = 127

Therefore, the value for common factors is 127.

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 = 50086254666/(1x127)

LCM = 50086254666/127

LCM = 394379958

Thus, we can understand that the LCM of 642,691,889,127 is 394379958.
