Given numbers are 253,122,642,604,421

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

The LCM of 253,122,642,604,421 is 1259721156012.

Find LCM of 253,122,642,604,421 with Prime Factorization

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

2 x 253 x 61 x 321 x 302 x 421 = 1259721156012

Therefore, the lowest common multiple of 253,122,642,604,421 is 1259721156012.

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.

253 x 122 x 642 x 604 x 421 = 5038884624048

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.

253 : 1, 11, 23, 253

122 : 1, 2, 61, 122

642 : 1, 2, 3, 6, 107, 214, 321, 642

604 : 1, 2, 4, 151, 302, 604

421 : 1, 421

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 253,122,642,604,421, is 1.

Now, the common factors can be found like this.

253:11x 23

122:2x 61

642:2x 3x 107

604:2x 2x 151

421:421

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 5038884624048/(1x4)

LCM = 5038884624048/4

LCM = 1259721156012

Thus, we can understand that the LCM of 253,122,642,604,421 is 1259721156012.
