Given numbers are 620,386,224,816

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

The LCM of 620,386,224,816 is 341748960.

Find LCM of 620,386,224,816 with Prime Factorization

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

2 x 2 x 2 x 2 x 155 x 193 x 14 x 51 = 341748960

Therefore, the lowest common multiple of 620,386,224,816 is 341748960.

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 386 x 224 x 816 = 43743866880

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

386 : 1, 2, 193, 386

224 : 1, 2, 4, 7, 8, 14, 16, 28, 32, 56, 112, 224

816 : 1, 2, 3, 4, 6, 8, 12, 16, 17, 24, 34, 48, 51, 68, 102, 136, 204, 272, 408, 816

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 620,386,224,816, is 2.

Now, the common factors can be found like this.

620:2x 2x 5x 31

386:2x 193

224:2x 2x 2x 2x 2x 7

816:2x 2x 2x 2x 3x 17

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 2 = 64

Therefore, the value for common factors is 64.

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 = 43743866880/(2x64)

LCM = 43743866880/128

LCM = 341748960

Thus, we can understand that the LCM of 620,386,224,816 is 341748960.
