Given numbers are 179,122,257,644,821

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

The LCM of 179,122,257,644,821 is 1483696300492.

Find LCM of 179,122,257,644,821 with Prime Factorization

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

2 x 179 x 61 x 257 x 322 x 821 = 1483696300492

Therefore, the lowest common multiple of 179,122,257,644,821 is 1483696300492.

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.

179 x 122 x 257 x 644 x 821 = 2967392600984

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.

179 : 1, 179

122 : 1, 2, 61, 122

257 : 1, 257

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

821 : 1, 821

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 179,122,257,644,821, is 1.

Now, the common factors can be found like this.

179:179

122:2x 61

257:257

644:2x 2x 7x 23

821:821

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

2 = 2

Therefore, the value for common factors is 2.

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 = 2967392600984/(1x2)

LCM = 2967392600984/2

LCM = 1483696300492

Thus, we can understand that the LCM of 179,122,257,644,821 is 1483696300492.
