Given numbers are 637,147,805,757

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

The LCM of 637,147,805,757 is 166362105.

Find LCM of 637,147,805,757 with Prime Factorization

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

7 x 7 x 13 x 3 x 115 x 757 = 166362105

Therefore, the lowest common multiple of 637,147,805,757 is 166362105.

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.

637 x 147 x 805 x 757 = 57062202015

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.

637 : 1, 7, 13, 49, 91, 637

147 : 1, 3, 7, 21, 49, 147

805 : 1, 5, 7, 23, 35, 115, 161, 805

757 : 1, 757

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 637,147,805,757, is 1.

Now, the common factors can be found like this.

637:7x 7x 13

147:3x 7x 7

805:5x 7x 23

757:757

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

7x 7x 7 = 343

Therefore, the value for common factors is 343.

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 = 57062202015/(1x343)

LCM = 57062202015/343

LCM = 166362105

Thus, we can understand that the LCM of 637,147,805,757 is 166362105.
