Given numbers are 630,631,622,826

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

The LCM of 630,631,622,826 is 7294277970.

Find LCM of 630,631,622,826 with Prime Factorization

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

2 x 7 x 45 x 631 x 311 x 59 = 7294277970

Therefore, the lowest common multiple of 630,631,622,826 is 7294277970.

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.

630 x 631 x 622 x 826 = 204239783160

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.

630 : 1, 2, 3, 5, 6, 7, 9, 10, 14, 15, 18, 21, 30, 35, 42, 45, 63, 70, 90, 105, 126, 210, 315, 630

631 : 1, 631

622 : 1, 2, 311, 622

826 : 1, 2, 7, 14, 59, 118, 413, 826

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 630,631,622,826, is 1.

Now, the common factors can be found like this.

630:2x 3x 3x 5x 7

631:631

622:2x 311

826:2x 7x 59

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 7 = 28

Therefore, the value for common factors is 28.

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 = 204239783160/(1x28)

LCM = 204239783160/28

LCM = 7294277970

Thus, we can understand that the LCM of 630,631,622,826 is 7294277970.
