Given numbers are 679,987,938,791,287

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

The LCM of 679,987,938,791,287 is 59436877458.

Find LCM of 679,987,938,791,287 with Prime Factorization

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

7 x 97 x 141 x 134 x 113 x 41 = 59436877458

Therefore, the lowest common multiple of 679,987,938,791,287 is 59436877458.

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.

679 x 987 x 938 x 791 x 287 = 142707942776658

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.

679 : 1, 7, 97, 679

987 : 1, 3, 7, 21, 47, 141, 329, 987

938 : 1, 2, 7, 14, 67, 134, 469, 938

791 : 1, 7, 113, 791

287 : 1, 7, 41, 287

7 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 679,987,938,791,287, is 7.

Now, the common factors can be found like this.

679:7x 97

987:3x 7x 47

938:2x 7x 67

791:7x 113

287:7x 41

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 = 142707942776658/(7x343)

LCM = 142707942776658/2401

LCM = 59436877458

Thus, we can understand that the LCM of 679,987,938,791,287 is 59436877458.
