Given numbers are 622,421,622,692

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

The LCM of 622,421,622,692 is 90604252.

Find LCM of 622,421,622,692 with Prime Factorization

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

2 x 311 x 1 x 421 x 1 x 346 = 90604252

Therefore, the lowest common multiple of 622,421,622,692 is 90604252.

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.

622 x 421 x 622 x 692 = 112711689488

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.

622 : 1, 2, 311, 622

421 : 1, 421

622 : 1, 2, 311, 622

692 : 1, 2, 4, 173, 346, 692

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 622,421,622,692, is 1.

Now, the common factors can be found like this.

622:2x 311

421:421

622:2x 311

692:2x 2x 173

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 311 = 1244

Therefore, the value for common factors is 1244.

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 = 112711689488/(1x1244)

LCM = 112711689488/1244

LCM = 90604252

Thus, we can understand that the LCM of 622,421,622,692 is 90604252.
