Given numbers are 637,406,721,134

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

The LCM of 637,406,721,134 is 254964346.

Find LCM of 637,406,721,134 with Prime Factorization

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

2 x 7 x 91 x 29 x 103 x 67 = 254964346

Therefore, the lowest common multiple of 637,406,721,134 is 254964346.

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 406 x 721 x 134 = 24986505908

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

406 : 1, 2, 7, 14, 29, 58, 203, 406

721 : 1, 7, 103, 721

134 : 1, 2, 67, 134

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 637,406,721,134, is 1.

Now, the common factors can be found like this.

637:7x 7x 13

406:2x 7x 29

721:7x 103

134:2x 67

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

2x 7x 7 = 98

Therefore, the value for common factors is 98.

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 = 24986505908/(1x98)

LCM = 24986505908/98

LCM = 254964346

Thus, we can understand that the LCM of 637,406,721,134 is 254964346.
