Given numbers are 644,254,318,842,106

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

The LCM of 644,254,318,842,106 is 5474806932.

Find LCM of 644,254,318,842,106 with Prime Factorization

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

2 x 53 x 322 x 127 x 3 x 421 x 1 = 5474806932

Therefore, the lowest common multiple of 644,254,318,842,106 is 5474806932.

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.

644 x 254 x 318 x 842 x 106 = 4642636278336

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.

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

254 : 1, 2, 127, 254

318 : 1, 2, 3, 6, 53, 106, 159, 318

842 : 1, 2, 421, 842

106 : 1, 2, 53, 106

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 644,254,318,842,106, is 2.

Now, the common factors can be found like this.

644:2x 2x 7x 23

254:2x 127

318:2x 3x 53

842:2x 421

106:2x 53

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 53 = 424

Therefore, the value for common factors is 424.

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 = 4642636278336/(2x424)

LCM = 4642636278336/848

LCM = 5474806932

Thus, we can understand that the LCM of 644,254,318,842,106 is 5474806932.
