Given numbers are 620,420,219,194,520

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

The LCM of 620,420,219,194,520 is 2397060120.

Find LCM of 620,420,219,194,520 with Prime Factorization

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

2 x 2 x 3 x 5 x 31 x 7 x 73 x 97 x 26 = 2397060120

Therefore, the lowest common multiple of 620,420,219,194,520 is 2397060120.

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 420 x 219 x 194 x 520 = 5752944288000

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

420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420

219 : 1, 3, 73, 219

194 : 1, 2, 97, 194

520 : 1, 2, 4, 5, 8, 10, 13, 20, 26, 40, 52, 65, 104, 130, 260, 520

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 620,420,219,194,520, is 1.

Now, the common factors can be found like this.

620:2x 2x 5x 31

420:2x 2x 3x 5x 7

219:3x 73

194:2x 97

520:2x 2x 2x 5x 13

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

2x 2x 2x 2x 2x 3x 5x 5 = 2400

Therefore, the value for common factors is 2400.

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 = 5752944288000/(1x2400)

LCM = 5752944288000/2400

LCM = 2397060120

Thus, we can understand that the LCM of 620,420,219,194,520 is 2397060120.
