Given numbers are 216,122,403,644

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

The LCM of 216,122,403,644 is 854898408.

Find LCM of 216,122,403,644 with Prime Factorization

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

2 x 2 x 54 x 61 x 403 x 161 = 854898408

Therefore, the lowest common multiple of 216,122,403,644 is 854898408.

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.

216 x 122 x 403 x 644 = 6839187264

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.

216 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 108, 216

122 : 1, 2, 61, 122

403 : 1, 13, 31, 403

644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 216,122,403,644, is 1.

Now, the common factors can be found like this.

216:2x 2x 2x 3x 3x 3

122:2x 61

403:13x 31

644:2x 2x 7x 23

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 2 = 8

Therefore, the value for common factors is 8.

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 = 6839187264/(1x8)

LCM = 6839187264/8

LCM = 854898408

Thus, we can understand that the LCM of 216,122,403,644 is 854898408.
