Given numbers are 638,134,131,497

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

The LCM of 638,134,131,497 is 2783063822.

Find LCM of 638,134,131,497 with Prime Factorization

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

2 x 319 x 67 x 131 x 497 = 2783063822

Therefore, the lowest common multiple of 638,134,131,497 is 2783063822.

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.

638 x 134 x 131 x 497 = 5566127644

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.

638 : 1, 2, 11, 22, 29, 58, 319, 638

134 : 1, 2, 67, 134

131 : 1, 131

497 : 1, 7, 71, 497

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 638,134,131,497, is 1.

Now, the common factors can be found like this.

638:2x 11x 29

134:2x 67

131:131

497:7x 71

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

2 = 2

Therefore, the value for common factors is 2.

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 = 5566127644/(1x2)

LCM = 5566127644/2

LCM = 2783063822

Thus, we can understand that the LCM of 638,134,131,497 is 2783063822.
