Given numbers are 638,831,119,697

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

The LCM of 638,831,119,697 is 2586738462.

Find LCM of 638,831,119,697 with Prime Factorization

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

17 x 638 x 831 x 7 x 41 = 2586738462

Therefore, the lowest common multiple of 638,831,119,697 is 2586738462.

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 831 x 119 x 697 = 43974553854

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

831 : 1, 3, 277, 831

119 : 1, 7, 17, 119

697 : 1, 17, 41, 697

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 638,831,119,697, is 1.

Now, the common factors can be found like this.

638:2x 11x 29

831:3x 277

119:7x 17

697:17x 41

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

17 = 17

Therefore, the value for common factors is 17.

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 = 43974553854/(1x17)

LCM = 43974553854/17

LCM = 2586738462

Thus, we can understand that the LCM of 638,831,119,697 is 2586738462.
