Given numbers are 620,961,398,279

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

The LCM of 620,961,398,279 is 34423020.

Find LCM of 620,961,398,279 with Prime Factorization

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

2 x 31 x 10 x 31 x 199 x 9 = 34423020

Therefore, the lowest common multiple of 620,961,398,279 is 34423020.

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.

620 x 961 x 398 x 279 = 66161044440

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.

620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620

961 : 1, 31, 961

398 : 1, 2, 199, 398

279 : 1, 3, 9, 31, 93, 279

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 620,961,398,279, is 1.

Now, the common factors can be found like this.

620:2x 2x 5x 31

961:31x 31

398:2x 199

279:3x 3x 31

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

2x 31x 31 = 1922

Therefore, the value for common factors is 1922.

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 = 66161044440/(1x1922)

LCM = 66161044440/1922

LCM = 34423020

Thus, we can understand that the LCM of 620,961,398,279 is 34423020.
