Given numbers are 388,973,417,691

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

The LCM of 388,973,417,691 is 782607252.

Find LCM of 388,973,417,691 with Prime Factorization

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

139 x 388 x 7 x 3 x 691 = 782607252

Therefore, the lowest common multiple of 388,973,417,691 is 782607252.

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.

388 x 973 x 417 x 691 = 108782408028

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.

388 : 1, 2, 4, 97, 194, 388

973 : 1, 7, 139, 973

417 : 1, 3, 139, 417

691 : 1, 691

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 388,973,417,691, is 1.

Now, the common factors can be found like this.

388:2x 2x 97

973:7x 139

417:3x 139

691:691

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

139 = 139

Therefore, the value for common factors is 139.

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 = 108782408028/(1x139)

LCM = 108782408028/139

LCM = 782607252

Thus, we can understand that the LCM of 388,973,417,691 is 782607252.
