Given numbers are 397,155,577,620

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

The LCM of 397,155,577,620 is 142022780.

Find LCM of 397,155,577,620 with Prime Factorization

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

5 x 31 x 397 x 1 x 577 x 4 = 142022780

Therefore, the lowest common multiple of 397,155,577,620 is 142022780.

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.

397 x 155 x 577 x 620 = 22013530900

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.

397 : 1, 397

155 : 1, 5, 31, 155

577 : 1, 577

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 397,155,577,620, is 1.

Now, the common factors can be found like this.

397:397

155:5x 31

577:577

620:2x 2x 5x 31

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

5x 31 = 155

Therefore, the value for common factors is 155.

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 = 22013530900/(1x155)

LCM = 22013530900/155

LCM = 142022780

Thus, we can understand that the LCM of 397,155,577,620 is 142022780.
